IOS implements shake operations

To achieve the function of shake 1, similar to WeChat shake 1

Method 1: The data of accelerometer is analyzed to determine whether the shake operation is carried out (relatively complex).

Method 2: Shake comes with iOS to monitor API (very simple)

This paper introduces method 2:

Judge the steps of shake 1:

  1. Start shaking detected
　- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event{

　　　　　　// It can be done when detected 1 Some processing

　　　　}
  1. Shake 1 shake is cancelled or interrupted
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{

　　　　}
  1. Shaking ends
　- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{

　　　　// It can be done after it is finished 1 Some processing

　　　　}

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