UITapGestureRecognizer与UIPanGestureRecognizer应用

UITapGestureRecognizer与UIPanGestureRecognizer应用：

一：UITapGestureRecognizer应用:

- （void）singleOne:(UITapGestureRecognizer *)sender { }//将相应事件发生时的动作写入函数
- （void）singleTwo:(UITapGestureRecognizer *)sender { }
- （void）doubleOne:(UITapGestureRecognizer *)sender { }
- （void）doubleTwo:(UITapGestureRecognizer *)sender { }

UITapGestureRecognizer *singleOne = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleOne:)];  
singleOne.numberOfTouchesRequired = 1;    //触摸点个数，另作：[singleOne setNumberOfTouchesRequired:1];
singleOne.numberOfTapsRequired = 1;    //点击次数，另作：[singleOne setNumberOfTapsRequired:1];

UITapGestureRecognizer *singleTwo = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTwo:)];  
singleTwo.numberOfTouchesRequired = 2; 
singleTwo.numberOfTapsRequired = 1; 

UITapGestureRecognizer *doubleOne = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleOne:)];  
doubleOne.numberOfTouchesRequired = 1; 
doubleOne.numberOfTapsRequired = 2; 

UITapGestureRecognizer *doubleTwo = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTwo:)];  
doubleTwo.numberOfTouchesRequired = 2; 
doubleTwo.numberOfTapsRequired = 2; 

[singleOne requireGestureRecognizerToFail:doubleOne]; //防止：双击被单击拦截[singleTwo requireGestureRecognizerToFail:doubleTwo]; //防止：双击被单击拦截

[self.view addGestureRecognizer:singleOne];  
[self.view addGestureRecognizer:singleTwo]; 
[self.view addGestureRecognizer:doubleOne]; 
[self.view addGestureRecognizer:doubleTwo]; 
[singleOne release];
[singleTwo release];
[doubleOne release];
[doubleTwo release];
