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];
