Basic UIGesture Recognizers in iOS App Development:

Here is the list of built-in gesture recognizers that Apple offers and that you, most likely, use every day in all kinds of android or iOS mobile apps development.

  1. Tap gesture recognizer
  2. Swipe gesture recognizer
  3. Pan gesture recognizer
  4. Pinch gesture recognizer
  5. Rotation gesture recognizer

1. Tap UIGesture Recognizer in iOS App Development:

It can be used to handle single or multiple taps, either with one or more fingers. Tapping is one of the most usual gestures that users make.

2. Swipe UIGesture Recognizer in iOS App Development :

3. Pan UIGesture Recognizer in iOS App Development :

4. Pinch UIGesture Recognizer in iOS App Development :

When you view photos on the Photos app and you use your two fingers to zoom in or out to a photo, then you perform a pinch gesture. As you understand, pinching requires two fingers. An object of this class is usually handy to change the transform of a view, and more specifically its scale.

5. Rotation UIGesture Recognizer in iOS App Development :

In accordance with the previous gesture, rotation is used to rotate a view using two fingers.

Other UIGesture Recognizers in iOS App Development:

  1. LongPress GestureRecognizer
  2. ScreenEdgePanGestureRecognizer

1. LongPress Gesture Recognizer :

An object of that class monitors for long-press gestures happening on a view. The pressing must last long enough in order to be detected, and the finger or fingers should not move a lot around the pressed point otherwise the gesture fails.

2. ScreenEdgePan Gesture Recognizer :

This one is similar to the swipe gesture, but with a great difference: The finger movement should always begin from an edge of the screen.
