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 


2) Shake 1 shake is cancelled or interrupted

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


3) 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
