To realize the function of shaking, it is similar to WeChat's shaking
Method 1: By analyzing the accelerometer data, we can determine whether the shake operation has been performed (more complicated)
Method 2: iOS comes with Shake monitoring API (very simple)
Method 2 of this article:
To determine the steps to shake:
1) The start of shaking is detected
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event{
//After detection, some processing can be done
}
2) Shake is cancelled or interrupted
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{
}
3) Shake ends
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{
//After the end, you can do some processing
}
The above three methods can be directly used without import class or Delegate.
