IOS開發之觸摸與點擊事件：UITapGestureRecognizer與UIPanGestureRecognizer應用

UITapGestureRecognizer與UIPanGestureRecognizer應用：    

一：UITapGestureRecognizer應用:

- （void）singleOne:(UITapGestureRecognizer *)sender { }//將相應事件發生時的動作寫入函數
- （void）singleTwo:(UITapGestureRecognizer *)sender { }
- （void）doubleOne:(UITapGestureRecognizer *)sender { }
- （void）doubleTwo:(UITapGestureRecognizer *)sender { }
UITapGestureRecognizer *singleOne = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleOne:)];  
singleOne.numberOfTouchesRequired = 1;    //觸摸點個數，另作：[singleOne setNumberOfTouchesRequired:1];
singleOne.numberOfTapsRequired = 1;    //點擊次數，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：雙擊被單擊攔截[singleTwo requireGestureRecognizerToFail:doubleTwo]; //防止：雙擊被單擊攔截
[self.view addGestureRecognizer:singleOne];  
[self.view addGestureRecognizer:singleTwo]; 
[self.view addGestureRecognizer:doubleOne]; 
[self.view addGestureRecognizer:doubleTwo]; 
[singleOne release];
[singleTwo release];
[doubleOne release];
[doubleTwo release];
