Spinner starts at non zero index value

Is it possible to make the value that the spinner starts at some non zero index as opposed to zeroth index? So you could still spin up to zeroth index value, but it would start at some non zero index value.

facing issue on sending selected row value from downpicker to uiviewcontroller?

• (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component

From the above method am able to get the selected row value in downpicker.m but i need to pass this value to my viewcontroller. Could anyone please help me on this?

Multiple Down Pickers

When I set up multiple down pickers in the same pages, If I choose an option for one, it disables all the others.

Is there a way to change the font?

Cocoapods integration

Will be possible to install this picker using cocoapods in the future?

Thanks.

Suggestion

The picker accepts strings, instead, it should accept objects as options and should have description text to show in picker to every corresponding model object

Disabled field

After open and close the downpicker several times, it turns disable, and can't be opened again.

Multiple DropDown usage in One ViewController

I am having a weird issue,

here is what i am doing

 self.maxPricePicker = [[DownPicker alloc] initWithTextField:self.maxPrice withData:self.mainPricesArray];
    [self.maxPricePicker setPlaceholder:@"Max. Price"];

    self.minPricePicker = [[DownPicker alloc] initWithTextField:self.minPrice withData:self.mainPricesArray];
    [self.minPricePicker setPlaceholder:@"Min. Price"];

    self.sizePicker = [[DownPicker alloc] initWithTextField:self.sizeUnit withData:@[@"Sq. Feet", @"Marla", @"Kanal"]];
    [self.sizePicker setPlaceholder:@"Select Size Unit"];

However it seems to me that only MinPrice picker works. When i click on it, suddenly all the picker values change to initial value? Also when i try to pick through other pickers i get a crash at

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    self->textField.text = [dataArray objectAtIndex:row];

    if([self.delegate respondsToSelector:@selector(pickerView:didSelectIndex:)])
        [self.delegate pickerView:pickerView didSelectIndex:row];
}

at  self->textField.text = [dataArray objectAtIndex:row];

textField and pickerView are nil. Not sure why the MinPrice picker is working and others not? and why their value change first time when i click on minPrice

Add an exmple code

Please add an example code with both approaches.
Thanks

Not Using Built(in Binary Protection )Stack Smashingx EMpos- es App Components to kemory Corruption Attacks

Description
Rtack smashing protection has not been implemented in components included in the application. When an application is
compiled with stack smashing protectionB a known value or XcanaryX is placed on the stack directly before the local variables
to protect the saved base pointerB saved instruction pointerB and function arguments. The value of the canary is verified upon
the function return to see if it has been overwritten. The compiler uses a heuristic to intelligently apply stack protection to a
functionB typically functions using character arrays.
This is a very simple best practice that hardens your app with little to no downside. Memory corruption vulnerabilities can be
very hard to track downB but can be extremely severe.
One thing to note, it is possible that an included binary does not have these protections and it is possible that a third party
would have to correct the problem. In a rare edge caseB Oamarin does include a library called vlMqh#hple)hmmg/t that is not
compiled with RRP but may not be vulnerable because it is an empty file. Ysers should validate that it is in fact empty before
hiding that specific result.

Steps To Reproduce
This test checks if the individual components inside the compiled binary used stack canaries to prevent buffer overflows.

Business Impact
This app does not protect against a specific type of attack that can expose the app to an attacker performing custom actions.
These custom actions could potentially give them access to sensitive information from the app or the device.

Recommended Fix
In OCodeB under the Nuild Rettings for the appB go to the XOther C FlagsX section and add in )>/ hu")mpt du tp)hvv.

"exceeds maximum index value of NSNotFound - 1"

Just created a picker with this

self.transactionTypes = [[NSMutableArray alloc] initWithArray:@[@"Buy", @"Rent", @"Share"]];
self.transactionTypePicker = [[DownPicker alloc] initWithTextField:self.transactionTypeField
                                                              withData:self.transactionTypes];

Then, when I selected the DropDown, got this error

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSMutableIndexSet addIndexesInRange:]: Range {2147483647, 1} exceeds maximum index value of NSNotFound - 1'

EDIT: I just found out that the problem occurs when there is some text in the Text Field (set in the Storyboard) so, in this lines was where the error shows up.

    //If the text field is empty show the place holder otherwise show the last selected option
    if (self->textField.text.length == 0)

      self->textField.placeholder = self->placeholderWhileSelecting;

    {

How to populate with Date or Time

Hi there,

I am using this in a project and so far it's been very easy to use and setup, thanks!

One issue I have however is I want to use it for multiple fields in one view... Some of which are date fields.

Is there an easy way of identifying DownPicker as using a standard (and infinite) dataset such as date or time?

Many thanks!

Liam

Add "set default option" feature

It would be great to add a property to set a default selected option from the dataArray. This way, picker would show a selected option since the beginning.

After set selected element to 0 it shows placeholder instead of element from array

After set selected element to 0 it shows placeholder instead of element from array.

[self.downPicker setSelectedIndex:0];

but

[self.downPicker getValueAtIndex:0];

returns right value

Installation Problem with CocoaPods

I've install DownPicker using Cocoapods and when I built the project this error has appeared:

error: /Users/ernsferrari/Library/Developer/Xcode/DerivedData/Prueba-cvmgkwpczwcrzkgbqwypmbspepuv/Build/Products/Debug-iphonesimulator/DownPicker/DownPicker.bundle: No such file or directory

The version of DownPicker is 0.1.34

Thank you for your help!

Different Display and Return Values

Can we have this work like a standard drop down for whom the display and return values can be specified

Dropdown Icon Pixelated on iPhone 6

The dropdown icon is only available in standard resolution, which makes it look pixelated on iPhone 6.
We should include the following icons:
downArrow.png (32x24) [Already exists]
[email protected] (64x48)
[email protected] (96x72)

I'd be glad to make and test these if you have a large source image I can start with.

Thanks!

James

Text inside text field is selectable

It would be great to avoid text selection inside a text field used as a DownPicker.

pickerValueChanged not called for first object

Heyo

In my app it appears that pickerValueChanged: is never called for the very first object in the pickers array. What's up with that ?

Localize "Done" button

The "Done" button can't be localized (without modifying the code) because it's hardcoded to that string:

UIBarButtonItem* doneButton = [[UIBarButtonItem alloc]
                               initWithTitle:@"Done"
                               style:UIBarButtonItemStyleDone
                               target:self
                               action:@selector(doneClicked:)];

Could not customise picker's toolbar.

Please expose picker's toolbar for easier customisation.

UIDownPicker how to use?

hi ~I am confused that UIDownPicker example code how to use?
please give me more detail to use,thx

missing CFBundleVersion

Info.plist is missing CFBundleVersion, due to which the app fails to install second time on simulator - please add

<key>CFBundleVersion</key>
 <string>0.1.34</string>

Why using @synthesize?

One question, why do you use this?

@synthesize text;
@synthesize selectedIndex;

@synthesize is no longer needed.

Last merged changed not included in pod
