#Quayboard

A keyboard accessory view that blends in with the default iOS keyboard, providing an additional set of customisable keys.

##Installation

There are a couple of ways to include Quayboard in your Xcode project.

###Subproject

This method is demonstrated in the included example project (example/QuayboardExample.xcodeproj).

1. Drag the Quayboard.xcodeproj file into your Project Navigator (⌘1) from the Finder. This should add Quayboard as a subproject of your own project (denoted by the fact that it appears as in a rectangle and you should be able to browse the project structure).

2. In your Project's target, under the Build Phases tab, add libQuayboard.a and QuayboardResources.bundle under 'Target Dependencies'.

3. Expand the Quayboard subproject and drag the QuayboardResources.bundle into your 'Copy Bundle Resources' build phase.

4. Build your project (⌘B). All going well you should get a 'Build Succeeded' notification. This signifies that you're ready to implement Quayboard in your project.

###Cocoapods

Quayboard can be installed very easily if you use Cocoapods with your projects. The podspec is included in the Github repository, and is also available through cocoapods.org.

Simply add the project to your Podfile by adding the line:

pod 'Quayboard'

And run pod update in terminal to update the pods you have included in your project.

You can also specify a version to include, such as 0.1.0:

pod 'Quayboard', '0.1.0'

For more information on how to add projects using Cocoapods, read their documentation on Podfiles.

##Implementing Quayboard

At the top of the header file for the view controller you want to implement Quayboard in, include Quayboard:

#import <Quayboard/Quayboard.h>

The view controller should also implement JSMQuayboardBarDelegate in order to receive notification that a key was pressed.

@interface MyViewController : UIViewController <JSMQuayboardBarDelegate>

In the viewDidLoad method, create an instance of JSMQuayboardBar, set the delegate of the instance as self and set it as the inputAccessoryView of the UITextField or UITextView you wish to implement on. For the purposes of this explanation, we're going to use a UITextView.

JSMQuayboardBar *quayboardBar = [[JSMQuayboardBar alloc] initWithFrame:CGRectMake( 0, 0, viewSize.width, height )];
quayboardBar.delegate = self;
self.textView.inputAccessoryView = quayboardBar;

You can then implement as many keys as you like. They will be evenly distributed across the length of the keyboard.

[quayboardBar addKeyWithValue:@"1"];
[quayboardBar addKeyWithValue:@"2"];
[quayboardBar addKeyWithValue:@"3"];
[quayboardBar addKeyWithValue:@"4"];
[quayboardBar addKeyWithValue:@"5"];
[quayboardBar addKeyWithTitle:@"⇥" andValue:@"\t"];

The final step is to implement the delegate method so that the textview is updated as expected. Here's an example (as shown in the example project) for updating a UITextView when a key is pressed:

- (void)quayboardBar:(JSMQuayboardBar *)quayboardBar keyWasPressed:(JSMQuayboardButton *)key {
	// Find the range of the selected text
	NSRange range = self.textView.selectedRange;
	
	// Get the relevant strings
	NSString *firstHalfString = [self.textView.text substringToIndex:range.location];
	NSString *insertingString = key.value;
	NSString *secondHalfString = [self.textView.text substringFromIndex:range.location+range.length];
	
	// Update the textView's text
	self.textView.scrollEnabled = NO;
	self.textView.text = [NSString stringWithFormat: @"%@%@%@", firstHalfString, insertingString, secondHalfString];
	self.textView.scrollEnabled = YES;
	
	// More the selection to after our inserted text
	range.location += insertingString.length;
	range.length = 0;
	self.textView.selectedRange = range;
}

Now Build and Run (⌘R). You should be presented with the Quayboard bar when you select the textview that you implemented it on. Pressing the keys will update the textview. Success feels good. Reward yourself with a Crunchie bar or something.
