CHITouchySuperButton

CHITouchySuperButton is a drop-in UIButton subclass that allows you to create and customize a highly interactive button in just a few lines of code. This class is compatible with the UIView animatable properties: transform, alpha, center, frame, bounds, and backgroundColor. This class is widely used in all SongShift apps to make it feel a lot more interactive. This package is only compatible with iOS apps and targets iOS 10+.

To install CHITouchySuperButton, you must either manually add the source files or use Swift Package Manager. To install with Swift Package Manager, follow these instructions from Apple's official documentation.

1. Open your app’s project settings, select your app target, and navigate to its General pane.
2. Click the + button in the “Frameworks, Libraries, and Embedded Content” section and select the local package’s library to link it into your app target.
3. Add this package by clicking "Add Other", followed by "Add Package Dependency", and then paste the packages GitHub URL.

The usage of CHITouchySuperButton is quite simple. Start by importing the module:

import CHITouchySuperButton

Then, create an instance of CHITouchySuperButton like you would with a standard UIButton. This can be done with interface builder, or programmatically:

let button = CHITouchySuperButton(frame: .zero)
// add a target for .touchUpInside just like a normal UIButton
button.addTarget(self, action: #selector(buttonPressed(_:)), for: .touchUpInside)
button.backgroundColor = UIColor.systemBlue
button.layer.masksToBounds = true
button.layer.cornerRadius = 13
button.setTitle("Touchy Super Button", for: .normal)
button.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(button)

view.addConstraints([
    button.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 30),
    button.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -30),
    button.centerYAnchor.constraint(equalTo: view.centerYAnchor),
    button.heightAnchor.constraint(equalToConstant: 65)
])

Now, to tell CHITouchySuperButton how you want it to look when pressed down and released, you implement two TouchBlock's:

// tell CHITouchySuperButton what to do when pressed down
button.buttonPressed = { button in
    // modify transform, alpha, center, frame, bounds, or backgroundColor
    button?.transform = CGAffineTransform(scaleX: 0.92, y: 0.92)
}

// tell CHITouchySuperButton what to do when released
button.buttonReleased = { button in
    // do NOT put your actions here, just your animations. use addTarget to add an action.
    button?.transform = .identity
}

That's it! This above code will produce the "Transform" effect that is at the top of this README.

By default, the touchy button will produce haptic feedback when released. To disable this, simply set hapticFeedbackEnabled to false on your CHITouchySuperButton.
