(3) Summary

--First create different types of gesture recognition based on what you need, such as:

Uitapgesturerecognizeruiswipegesturerecognizeruipinchgesturerecognizeruirotategesturerecognizeruipangesturerecognizer

--Then use the Addgesturerecognizer method to add these gesture objects to the desired object, such as:

[Self.imgview Addgesturerecognizer:swipe];

--Of course, these gestures can use Addtarget to add some event detection, such as:

Uipinchgesturerecognizer *pinch=[[uipinchgesturerecognizer alloc]initwithtarget:self Action: @selector (PinchView:) ];

--Also, gesture recognition has some more commonly used proxy methods, such as whether the following methods allow multiple gestures to work simultaneously:

-(BOOL) Gesturerecognizer: (Uigesturerecognizer *) Gesturerecognizer Shouldrecognizesimultaneouslywithgesturerecognizer: (Uigesturerecognizer *) othergesturerecognizer{    return YES ;}
