Implementation of one shake

Implementation of one shake

The shake function is similar to the shake function.

Method 1: analyze the accelerated counting data to determine whether the data has been shaken (complicated)
Method 2: the built-in Shake monitoring API (very simple)

This article introduces Method 2:

Steps for judging the shaking:

1) start shaking Detected

-(Void) motionBegan :( UIEventSubtype) motion withEvent :( UIEvent *) event {

// Do some processing after detection

}

2) Shake canceled or interrupted

-(Void) motionCancelled :( UIEventSubtype) motion withEvent :( UIEvent *) event {

}

3) Shake ends

-(Void) motionEnded :( UIEventSubtype) motion withEvent :( UIEvent *) event {

// Do some processing after the end

}

 

All the above three methods inherit the UIResponder. h In UIKit and can be directly used without the import class or the Delegate inheritance.
