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.

view.pan([
    .began:   panBegan,
    .changed: panChanged,
    .ended:   panEnded
])

// func panBegan(pan: UIPanGestureRecognizer)
// func panChanged(pan: UIPanGestureRecognizer)
// func panEnded(pan: UIPanGestureRecognizer)

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)
