IOS开发之触摸与点击事件：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];
