mlpautocompletetextfield's Issues

how to know if the table is showing?

Sorry, I might be missing something very obvious, but is there a way to tell if the tableview is currently expanded?

I tried subclassing and putting a setter on autoCompleteTableViewHidden but that's not it.

I need to change my layout whenever the table is open.

Thanks in advance!

Can't find asciiLevenshteinDistanceWithString

I use cocoapod and added all your files per instruction.
Yet when I run the app I get Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString asciiLevenshteinDistanceWithString:]: unrecognized selector sent to instance 0x9d5bb40'

Any idea?

String Hiding when suggestions is of poor quality

Not sure if this is the right place to put it as it's already in the readme, but do you have plans to add String Hiding anytime soon?

Btw thanks for this awesome pod!

Can't click sugestion when using the control as a navigation top bar item

My issue is this, i can't touch the suggestion table view cells outside the frame of the navigation bar view, i try to alter the code in the library but the results are the same, i see the reports about the control fixed in some other issues like using the control in a tableview, the problem here is similar because the control is inside a navigation bar item using storyboard, i think is because the view of the tableview is taking all the touch events apart of the touch events inside the navigation top bar frames.

What can i do to fix this issue, i can bring more information of the proyect if you want. Thanks for this amazing library. Sorry for my bad english.

2 Xcode Compiler warnings for unused variables

When I Archive my project, Xcode 5.1.1 shows 2 compiler warnings for unused variables.
There are several ways to solve this, see for example:
http://stackoverflow.com/questions/5451123/how-can-i-get-rid-of-an-unused-variable-warning-in-xcode

I have chosen to use:

__unused

1. MLPAutoCompleteTextField/MLPAutoCompleteTextField.m:600:10: Unused variable 'classSettingSupported'

2. MLPAutoCompleteTextField/MLPAutoCompleteTextField.m:919:23: Unused variable 'firstObject'

Not working on my app.

I'm studying iOS programming and I am implementing MLPAutoCompleteTextField to my simple app. I followed instructions and also referred to the sample project. But when I build & run my project, it is successfully compiled but the suggestions are not displayed.
Here's how it looks:http://d.pr/i/Uv3D

AddQuoteViewController.h

#import <UIKit/UIKit.h>
#import "MLPAutoCompleteTextFieldDataSource.h"
#import "MLPAutoCompleteTextFieldDelegate.h"

@class MLPAutoCompleteTextField;
@interface AddQuoteViewController : UIViewController <UITextFieldDelegate, MLPAutoCompleteTextFieldDataSource, MLPAutoCompleteTextFieldDelegate>

@property (strong, nonatomic) IBOutlet MLPAutoCompleteTextField *authorTextField;
- (IBAction)saveQuoteButton:(id)sender;
@end

AddQuoteViewController.m

#import "AddQuoteViewController.h"
#import "MLPAutoCompleteTextField.h"
#import "AuthorAutoSuggestTableViewCell.h"
#import <QuartzCore/QuartzCore.h>

@implementation AddQuoteViewController
- (void)viewDidLoad {
    [super viewDidLoad];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShowWithNotification:) name:UIKeyboardDidShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHideWithNotification:) name:UIKeyboardDidHideNotification object:nil];

    [self.authorTextField setBorderStyle:UITextBorderStyleRoundedRect];
}

- (void)keyboardDidShowWithNotification:(NSNotification *)aNotification {
    [self.author setAlpha:0];
}

- (void)keyboardDidHideWithNotification:(NSNotification *)aNotification {
    [self.author setAlpha:1];
    [self.authorTextField setAutoCompleteTableViewHidden:NO];
}

- (NSArray *)possibleAutoCompleteSuggestionsForString:(NSString *)string {
    NSArray *sample = @[@"Ape", @"Bird", @"Cat", @"Dog"];
    return sample;
}

- (BOOL)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
          shouldConfigureCell:(UITableViewCell *)cell
       withAutoCompleteString:(NSString *)autocompleteString

}

Crash when typing too fast

I'm testing on an iPad 1 running iOS 5.1. There is a concurrency problem where a crash occurs in MLPAutoCompleteFetchOperation because sentinelSemaphore is signalled in -[MLPAutoCompleteFetchOperation cancel] while it is nil because it has never been created.

If a MLPAutoCompleteTextFieldDelegate doesn't implement autoCompleteTextField:possibleCompletionsForString:completionHandler: then the semaphore will never be created in -[MLPAutoCompleteFetchOperation main]. Therefore if the user is typing fast enough that fetchAutoCompleteSuggestions gets called a second time while there is an operation on the queue, it will get cancelled which will call the operation's cancel method which attempts to signal the semaphore which was never created.

I suggest putting a guard to make sure the semaphore isn't nil in the -[MLPAutoCompleteFetchOperation cancel] method like so:

- (void) cancel
{
    if (sentinelSemaphore) dispatch_semaphore_signal(sentinelSemaphore);
    [super cancel];
}

Crash on iOS 5.1 due to lack of attributed text support on UILabel before iOS 6

The code checks for this case then asserts. Therefore MLPAutoCompleteTextField crashes on iOS versions less than 6. The README states it supports iOS 5.0+

lines 249-250 of MLPAutoCompleteTextField.m (as of commit 0443f02):

    BOOL attributedTextSupport = [cell.textLabel respondsToSelector:@selector(setAttributedText:)];
    NSAssert(attributedTextSupport, @"Attributed strings on UILabels are  not supported before iOS 6.0");

Using UITextFieldDelegate

I need to set my autocomplete field to also use a UITextField delegate, however doing so I get the following:

Obj-C -[MLPAutoCompleteTextField title]: unrecognized selector sent to instance 0x17647d70

Love this component by the way, works great otherwise.

Result tableView appears transparent

The result tableView appears transparent always, I tried to set the property autoCompleteTableBackgroundColor but nothing happens still transparent

Styling the autocomplete table view

Is there any easy way to style the autocomplete table view positioning, border color/width/radius, text color/positioning etc. or do I have to tamper with the source code?

For example the text in the autocomplete table view is black in the example project but in my project it's light blue, and has a border that also is light blue.

So this is just a question on styling the appearance of the autocomplete table view and not really an issue, but I didn't know where else to ask.

Scroll Table

Hello all!
I want to scroll table view with autocomplete to top, after user typer in text field. It's possible with this component?

Suggestions are not showing up on iPhone 4 IOS 6.1.3

Any Ideas ?

Unable to show self.autoCompleteTableView on the popover view in iPad in XCode 6 development

I'm using your github project for my developments. Thanks for this. This is very simple to use and I did some changes according to our requirements.

Earlier I used this in xcode 5.1 development and now i converted this into xcode 6.1 (Objective C). But when i run the same application in ios 7 and 8 in iPad by using xcode 6, self.autoCompleteTableView is not showing the top view. It shows in the bottom view.

It was working well in xcode 5.1 build.

XCode 5.1 build

XCode 6.1 build

I want to show this as XCode 5.1 build.

Below is my code.

-(void)expandDropDownAutoCompleteTableForNumberOfRows:(NSInteger)numberOfRows
{
[self resetDropDownAutoCompleteTableFrameForNumberOfRows:numberOfRows];
if(numberOfRows && (self.autoCompleteTableViewHidden == NO)){
[self.autoCompleteTableView setAlpha:1];

    if(!self.autoCompleteTableView.superview){
        if([self.autoCompleteDelegate
            respondsToSelector:@selector(autoCompleteTextField:willShowAutoCompleteTableView:)]){
            [self.autoCompleteDelegate autoCompleteTextField:self
                               willShowAutoCompleteTableView:self.autoCompleteTableView];
        }
    }

    [self.superview bringSubviewToFront:self];

    UIView *rootView;
    if (gaiDevice == iPad)
    {
        rootView = [UIApplication sharedApplication].keyWindow;
        [rootView insertSubview:self.autoCompleteTableView aboveSubview:[UIApplication sharedApplication].keyWindow.rootViewController.view];

    }
    else
    {
        [rootView insertSubview:self.autoCompleteTableView
                   belowSubview:self];

        rootView = [self.window.subviews objectAtIndex:0];
        [rootView insertSubview:self.autoCompleteTableView
                   belowSubview:self];
    }

    [self.autoCompleteTableView setUserInteractionEnabled:YES];
    if(self.showTextFieldDropShadowWhenAutoCompleteTableIsOpen){
        [self.layer setShadowColor:[[UIColor blackColor] CGColor]];
        [self.layer setShadowOffset:CGSizeMake(0, 1)];
        [self.layer setShadowOpacity:0.35];
    }
} else {
    [self closeAutoCompleteTableView];
    [self restoreOriginalShadowProperties];
    [self.autoCompleteTableView.layer setShadowOpacity:0.0];
}

}

So how can I show this in iPad's top view on the popover in xcode 6 build??

Thank you!

How to reload this?

Let's say I have a service that fetches auto complete suggestions. I have to reload the data to show the web service response. Any ideas?

Tableview Keyboard Input Accessory not shown when using auto layout and storyboard

Hi,

I'm trying to get the tableview keyboard input accessory running but somehow can't get it working. After a bit of debugging I found out it's related the storyboard and using autolayout. When I disable auto layout the tableview is shown. When I enable autolayout the frame of the tableview is set to 0,0,0,0 I guess because the MLPAutoCompleteTextField has no dimensions yet. Hope you know how to fix this.

Thanks!

remove autocompleteString from custom UITableViewCell

Hi,

I'm trying to figure out a way to remove the autocompleteString from a custom UITableViewCell.

In the viewController:viewDidLoad I registered the custom UITableViewCell class & Nib with

registerAutoCompleteCellClass:forCellReuseIdentifier:
registerAutoCompleteCellNib:bundle:forCellReuseIdentifier:

then, in the delegate method

(BOOL)autoCompleteTextField:(MLPAutoCompleteTextField *)textField shouldConfigureCell:(UITableViewCell *)cell withAutoCompleteString:(NSString *)autocompleteString withAttributedString:(NSAttributedString *)boldedString forAutoCompleteObject:(id<MLPAutoCompletionObject>)autocompleteObject forRowAtIndexPath:(NSIndexPath *)indexPath

I tried to remove the autocompleteString from the custom cell

autocompleteString = nil; boldedString = nil; cell.textLabel.text = nil;

Unfortunately though, the autocompleteString keep showing inside the custom cell.
How to remove it ?

Thanks.

want to show suggestions only after entering 3 or more characters in text field

I felt suggestions for one or two characters are pretty irrelevant. Can i make some changes to the code so that suggestions are displayed only after 3 or more characters are entered into the text field ?

Memory leak of semaphore in iOS 5

On iOS 5 which doesn't use ARC, dispatch objects such as semaphores must be explicitly released. In MLPAutoCompleteFetchOperation sentinelSemaphore is created but never released. The semaphore will leak because without ARC, you need to call dispatch_release() when you're done with it. (see https://developer.apple.com/library/mac/documentation/Performance/Reference/GCD_libdispatch_Ref/Reference/reference.html#//apple_ref/doc/uid/TP40008079-CH1-SW2)

which says:

Dispatch Queues and Automatic Reference Counting

The behavior of dispatch queues in an automatic reference counting environment varies depending on the deployment target that you choose for a given build target.

• iOS 6 and later—Dispatch objects (including queues) are Objective-C objects, and are retained and released automatically.
• OS X 10.8 and later—Dispatch objects (including queues) are Objective-C objects, and are retained and released automatically.
• Earlier versions—Dispatch objects are custom objects. You must handle the reference counting manually by calling dispatch_retain and dispatch_release.

If you need to use manual reference counting in an ARC-enabled app with a later deployment target (for maintaining compatibility with existing code), you can disable Objective-C-based dispatch objects by adding -DOS_OBJECT_USE_OBJC=0 to your compiler flags.

Adding MLPAutoCompleteTextField to a view programitacally

Hi,
First of all thanks for a great plugin.
I'm using the example project and I've been trying to add the MLPAutoCompleteTextField to the MLPViewController programatically.
I've deleted the view.xib file, but I cannot seem to get the custom text field to appear in the view programatically. Could you please advise how I can achieve this. I've included my viewDidLoad implementation below.
Thanks again,
Patrick

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.autocompleteTextField = [[MLPAutoCompleteTextField alloc] initWithFrame:CGRectMake(10, 200, 300, 40)];
    self.autocompleteTextField.delegate = self;
    self.autocompleteTextField.autoCompleteDataSource = self;
    self.autocompleteTextField.autoCompleteDelegate = self;


    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShowWithNotification:) name:UIKeyboardDidShowNotification object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHideWithNotification:) name:UIKeyboardDidHideNotification object:nil];

    //Supported Styles:
    //[self.autocompleteTextField setBorderStyle:UITextBorderStyleBezel];
    //TODO[self.autocompleteTextField setBorderStyle:UITextBorderStyleLine];
    //[self.autocompleteTextField setBorderStyle:UITextBorderStyleNone];
    [self.autocompleteTextField setBorderStyle:UITextBorderStyleRoundedRect];


    //You can use custom TableViewCell classes and nibs in the autocomplete tableview if you wish.
    [self.autocompleteTextField registerAutoCompleteCellClass:[MLPCustomAutoCompleteCell class]
                                       forCellReuseIdentifier:@"CustomCellId"];

    [self.view addSubview:self.autocompleteTextField];


}

Features enhancement.

Hi Eddy,

First I wanted to say congrats about the great work with MLPAutoCompleteTextField. I started playing with it recently. So here are my goals:

a) I want to search on a large array of strings. I experimented with 10K and it is not bad (~1sec). Do you have any ideas how to optimize for larger arrays? Perhaps some caching?
b) I have already pre-sorted the array. Does it helps? I cannot seem to find in your code if it sorts the array or not.
c) How can I change your code so that the search takes place on multiple words?I want to do this because my array contains entries with multiple words. Basically what I want to achieve is this: the user types in one word, the word is matched as it does now, but then when the user types in a second word, then the second word is tried to be matched with the results of the first word. Could you point me to your code?
d) Finally you mention that you want to do have some ranking in the array of strings. How could I modify your code to address this?

Once again thank you for your help. Great work!

autoCompleteTableView shadow is not effected ?

hi Eddy,
i've applied these lines of code :
self.autoCompleteTableView.layer.masksToBounds=NO;
self.autoCompleteTableView.layer.shadowOffset=CGSizeMake(1,1);
self.autoCompleteTableView.layer.shadowRadius=5.0f;
self.autoCompleteTableView.layer.shadowOpacity=1;
self.autoCompleteTableView.layer.shadowColor=[UIColor orangeColor].CGColor;

in the method -setNoneStyleForAutoCompleteTableView
but,i couldn't see them on the tableview.

View hierarchy issue when displaying autoCompleteTableView

Hello,

I really appreciate your work on MLPAutoCompleteTextField. I would like to use it in our project, because it fits our requirements perfectly. But I am now facing an issue when the autoCompleteTableView is displayed. I am currently using v1.5 added to project via Pods.

Here is my situation:
I have to generate a mask view dynamically from out a mask model that I retrieve by a web service. The mask model contains various objects. I made a screenshot to make things easier. ;)

• Mask contains x groups (alternating cyan / blue color)
• Group contains x column (alternating yellow / orange color)
• Column contains x entries (alternating light / dark gray color)
• Entries contains a label (green color) and an inputField (white color)

Now I subclassed UIView a few times (Mask, Group, Column, Entry) and generate the view when receiving the maskModel from the server. In my testcase I used the MLPAutoCompleteField as inputField in every entry. Now here is my issue:

When I type into an inputField the tableView will be displayed. But as you can see it is overlayed by the next group view. I had set clipsToBounds and masksToBounds to NO in every view in the hierarchy. But it seems to have no effect. I inspected your code an found a possible issue. The tableView will be inserted as subview into the superview of the inputField (in my case it's the MaskEntry - grey color).

While browsing GitHub I found out, that you fixed an similar issue by adding the tableView to the root view. So I replaced my version by the current state. But that the table view is completely misplaced and won't be diplayed under the input field.

Is there anything I am doing wrong? Any solutions?

I would really appreciate some help!

Best regards,

autoCompleteDelegate used in the initialiser but is not yet set

The IBOutlet autoCompleteDelegate is accessed from the initializer (init-> initialize-> styleAutoCompleteTableForBorderStyle:), but the outlets are not set while the designated initializer chain is called, so delegate method autoCompleteTextField:shouldStyleAutoCompleteTableView:forBorderStyle: will never get called while the class is initializing

I created a pull request #73 that should fix this issue.

AutoCompleteTableView positioning

Hi,
I'm trying to move down the autocomplete table view, since it appears in the middle of the AutoCompleteTextfield and covers half of the text. Is there any property or method to achieve this ?
I tried with autoCompleteTableOriginOffset/setAutoCompleteTableOriginOffset (in both viewWillAppear and viewDidLoad), but nothing moves or changes.

I'm using XCode Version 5.1.1 (5B1008), iOS 7.1.1 with storyboard.

Thanks

TableView height should be adjustable

By default, the table height fits about 2.5 results. This value should be adjustable so one could take advantage of all space available, if desired.
Also, when the results are show as keyboard accessory, the heigh does not decrease when there are less autocomplete suggestions available (ie only one).
Moreover, I noticed that using the keyboard accessory, when there's no suggestions, there's still an invisible table or view on top of the keyboard, so I cannot tap the superview to dismiss the keyboard. This does not happen with the dropdown.

Autocomplete Table does not rearrange on orientation change

I am using the autocomplete on iPad, and my app supports any orientation. The autocomplete table is able to show up correctly in any orientation, but when it is already open and I rotate the device, the table does not follow the frame changes to match the new position of the text field.

iOS 8 (simulator): autoCompleteTableView doesn't appear

Trying to switch from iOS 7.1 to iOS 8, I noticed that the autoCompleteTableView doesn't appear anymore. I double checked that data is fetched correctly, so it should be something related to the tableview's visibility.
Instead of the tableview, only a bottom shadow appears.

Before typing

After typing

I'm on OSX 10.9.5 (Mavericks), using XCode 6.0.1 (6A317)
My app is written with Objective-C, no swift at all.

tapping on textfield empty table appear.

can you add the option to appear a empty table while its being load from the web service. or else we cant find whether the function is working or not.

in other words there should be activity indicator until the data is fetched from the server to app.

Is there a way of showing ONLY the results that have matched?

I already have a very long list of numbers and I'd like to see if there is anyway I can only show the results that have matched (at least by 1 letter) what the user has entered?
Any suggestions?

Suggestions z-index problem when in static UITableView cell

For the app I'm working on, there is a form with some textfields. The autocomplete works without a problem inside a regular view in a view controller, but there are some z-index issues when the autocomplete textfield is inside a static cell of a UITableView.

It's hard to show with screenshots, but you can see the form below with the autocomplete suggestions showing up. When you try and click on one it dismisses the dialog and selects the MRN field below the suggestions.

App get Stuck in iOS 7

I have used this library in my current project, but I dnt know what is the reason but this make the Device stuck even with opened keyboard too.

in Stack trace, I found it always raise this issue when i try too type and crashes at
dispatch_semaphore_wait(sentinelSemaphore, DISPATCH_TIME_FOREVER);
from -main method of MLPAutocompleteTextField.m

Very surprising part it that When i try to type something from Keyboard attached to machine then its not crashing but when i use the On screen keyboard of simulator It crashes everytime.

Just in iPhone 5, I have some fields not showed, it's there... but i can't see. Doesn't happen in simulator, only in iPhone 5. Does anyone knows why?

can't click on suggestion

I implement simple datasource for autocomplete list and show suggestions, but when i try to select one of the suggestion it do nothing.

I also try to implement some delegate methods like:

- (void)autoCompleteTextField:(MLPAutoCompleteTextField *)textField

       withAutoCompleteObject:(id<MLPAutoCompletionObject>)selectedObject
            forRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"select: %@", selectedString);
}

Nothing happens.

    } else {
        NSLog(@"selected string '%@' from autocomplete menu", selectedString);
    }
}

@end

If I uncomment the line [self.textField setAutoCompleteDataSource:[[GBProductAutocomplete alloc] init]]; in viewDidLoad the autocomplete will work, but I cannot figure out why I cannot drag from the outlet in the nib to connect the property.

TableView is clipped by super view

When the super view of the textField is small, the tableView is clipped. Is there is any way to add the table view as a subview to the window instead of its superview?, i tried to do that but the table view covered the half of the textField

Version 1.6 not installable with cocoapods

In the readme, it lists '~> 1.6' as the target for installing with cocoapods. When I tried pod install with that version, it gave me

[!] Unable to satisfy the following requirements:

Also, https://github.com/CocoaPods/Specs/tree/master/Specs/MLPAutoCompleteTextField only lists up to 1.5, so it seems like 1.5 should be the version in the readme instructions.

3 Xcode Compiler warnings for 64-bit architecture

When I compile in Xcode 5.1.1 for a 64-bit Simulator, I get 3 warnings.
I have added them here, incl. a proposed fix. I hope you can effectuate these changes.

1. MLPAutoCompleteTextField/NSString+Levenshtein.m:87:13: Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'int'

Proposed solution:

NSUInteger n = [dataA length];

2. MLPAutoCompleteTextField/NSString+Levenshtein.m:88:13: Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'int'

Proposed solution:

NSUInteger m = [dataB length];

3. MLPAutoCompleteTextField/MLPAutoCompleteTextField.m:239:50: Values of type 'NSInteger' should not be used as format arguments; add an explicit cast to 'long' instead

Proposed solution:

return [NSString stringWithFormat:@"{%ld,%ld}",(long)indexPath.section,(long)indexPath.row];

Storyboard demo

Could you please add a demo using storyboard.
I have problems figuring out how to connect textfields to datasources, and since I am using storyboards I think that a sample would help.

Thanks

Auto Suggestion based on user input

Is it possible to auto suggest item based on user input. fx. I have the following url "https://itunes.apple.com/search?term=" where users have to enter a search term?

I have tried to the following:

define baseURL @"https://itunes.apple.com/search?term="

• (void)autoCompleteTextField:(MLPAutoCompleteTextField *)textField
  possibleCompletionsForString:(NSString *)string
  completionHandler:(void (^)(NSArray *))handler
  {
  dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
  dispatch_async(queue, ^{
  if(self.simulateLatency){
  CGFloat seconds = arc4random_uniform(4)+arc4random_uniform(4); //normal distribution
  NSLog(@"sleeping fetch of completions for %f", seconds);
  sleep(seconds);
  }

  NSMutableArray* jsonObject = [[NSMutableArray alloc]init];
  NSMutableArray* suggestionlist = [[NSMutableArray alloc]init];
  NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",baseURL,textField.text]]];
  NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
  NSError* error;
  jsonObject = [NSJSONSerialization
                JSONObjectWithData:response
                options:0
                error:&error];
  
  for (int i = 0 ; i < jsonObject.count; i++) {
      NSString* artistName = [[jsonObject objectAtIndex:i] objectForKey:@"artistId"];
      [suggestionlist addObject:artistName];
  }
  

  handler(suggestionlist);
  });
  }

But I got the following error:

GAIUncaughtExceptionHandler(NSException ) (GAIUncaughtExceptionHandler.m:41): Uncaught exception: data parameter is nil
2014-05-15 11:49:54.224 MLPAutoCompleteDemo[6349:5503] GoogleAnalytics 2.0b4 void GAIUncaughtExceptionHandler(NSException *) (GAIUncaughtExceptionHandler.m:38): Bailing on multiple uncaught exceptions: data parameter is nil
2014-05-15 11:49:54.224 MLPAutoCompleteDemo[6349:5503] ** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'data parameter is nil'

Any suggestions why it is not working?
