Tactile is a safer and more idiomatic way to respond to gestures and control events. It lets you catch bugs at compile time and write more expressive code.

Usage

Tactile extends both UIView and UIControl classes.

UIView extensions

UIView+Tactile.swift

The on method

Use the on method to add gesture recognizers.

on(gesture:callback:)

let tap = UITapGestureRecognizer()
tap.numberOfTapsRequired = 3
tap.numberOfTouchesRequired = 2

view.on(tap, tapped)

// func tapped(tap: UITapGestureRecognizer)

on(gesture:state:callback:)

let pinch = UIPinchGestureRecognizer()

view.on(pinch, .Began, pinchBegan)

// func pinchBegan(pinch: UIPinchGestureRecognizer)

on(gesture:states:callback:)

let pan = UIPanGestureRecognizer()

view.on(pan, [.Began, .Ended], panBeganOrEnded)

// func panBeganOrEnded(pan: UIPanGestureRecognizer)

on(gesture:callbacks:)

let pinch = UIPinchGestureRecognizer()

view.on(pinch, [
  .Began: pinchBegan,
  .Ended: pinchEnded
])

// func pinchBegan(pinch: UIPinchGestureRecognizer)
// func pinchEnded(pinch: UIPinchGestureRecognizer)

The shorthand methods

Tactile defines 6 shorthand methods: longPress, pan, pinch, rotation, swipe and tap.

<shorthand>(callback:)

view.tap(tapped)

// func tapped(tap: UITapGestureRecognizer)

<shorthand>(state:callback:)

view.pinch(.Began, pinchBegan)

// func pinchBegan(pinch: UIPinchGestureRecognizer)

<shorthand>(states:callback:)

view.pan([.Began, .Ended], panBeganOrEnded)

// func panBeganOrEnded(pan: UIPanGestureRecognizer)

<shorthand>(callbacks:)

view.longPress([
  .Began: longPressBegan,
  .Ended: longPressEnded
])

// func longPressBegan(longPress: UILongPressGestureRecognizer)
// func longPressEnded(longPress: UILongPressGestureRecognizer)

The off method

Use the off method to remove gesture recognizers.

off(gesture:)

let tap = UITapGestureRecognizer()
view.on(tap, tapped)

// ...

view.off(tap)

off(gestureType:)

view.off(UITapGestureRecognizer.self)

off()

view.off()

Attaching a gesture recognizer to multiple views

With Tactile, you can attach the same gesture recognizer to multiple views.

let tap = UITapGestureRecognizer()
tap.numberOfTapsRequired = 3
tap.numberOfTouchesRequired = 2

firstView.on(tap, firstViewTapped)
secondView.on(tap, secondViewTapped)

UIControl extensions

UIControl+Tactile.swift

Use the on method to attach an event handler function for one or more control events.

on(event:callback:)

button.on(.TouchUpInside, tapped)

// func tapped(button: UIButton)

on(events:callback:)

button.on([.TouchUpInside, .TouchUpOutside], tapped)

// func tapped(button: UIButton)

on(callbacks:)

button.on([
  .TouchUpInside: tapped,
  .TouchUpOutside: cancelledTap
])

// func tapped(button: UIButton)
// func cancelledTap(button: UIButton)

Installation

Carthage

Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate Tactile into your Xcode project using Carthage, specify it in your Cartfile:

github "delba/Tactile" >= 1.0

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

You can install it with the following command:

$ gem install cocoapods

To integrate Tactile into your Xcode project using CocoaPods, specify it in your Podfile:

use_frameworks!

pod 'Tactile', '~> 1.0'
