IOS开发—手势操作（点击+滑动）

//单指单击  

UITapGestureRecognizer *singleFingerOne = [[UITapGestureRecognizer alloc] initWithTarget:self  

                                                                                  action:@selector(handleSingleFingerEvent:)];  

singleFingerOne.numberOfTouchesRequired = 1; //手指数  

singleFingerOne.numberOfTapsRequired = 1; //tap次数  

singleFingerOne.delegate = self;  

  

//单指双击  

UITapGestureRecognizer *singleFingerTwo = [[UITapGestureRecognizer alloc] initWithTarget:self  

                                                                                  action:@selector(handleSingleFingerEvent:)];  

singleFingerTwo.numberOfTouchesRequired = 1;  

singleFingerTwo.numberOfTapsRequired = 2;  

singleFingerTwo.delegate = self;  

  

//双指单击  

UITapGestureRecognizer *doubleFingerOne = [[UITapGestureRecognizer alloc] initWithTarget:self  

                                                                                  action:@selector(handleDoubleFingerEvent:)];  

doubleFingerOne.numberOfTouchesRequired = 2;  

doubleFingerOne.numberOfTapsRequired = 1;  

doubleFingerOne.delegate = self;  

  

UITapGestureRecognizer *doubleFingerTwo = [[UITapGestureRecognizer alloc] initWithTarget:self  

                                                                                  action:@selector(handleDoubleFingerEvent:)];  

doubleFingerTwo.numberOfTouchesRequired = 2;  

doubleFingerTwo.numberOfTapsRequired = 2;  

doubleFingerTwo.delegate = self;  

  

//如果不加下面的话，当单指双击时，会先调用单指单击中的处理，再调用单指双击中的处理  

[singleFingerOne requireGestureRecognizerToFail:singleFingerTwo];  

//同理双指亦是如此  

[doubleFingerOne requireGestureRecognizerToFail:doubleFingerTwo];  

  

[self.view addGestureRecognizer:singleFingerOne];  

[self.view addGestureRecognizer:singleFingerTwo];  

[self.view addGestureRecognizer:doubleFingerOne];  

[self.view addGestureRecognizer:doubleFingerTwo];  

 

//处理单指事件  

- (void)handleSingleFingerEvent:(UITapGestureRecognizer *)sender  

{  

    if (sender.numberOfTapsRequired == 1) {  

        //单指单击  

        NSLog(@"单指单击");  

    }else if(sender.numberOfTapsRequired == 2){  

        //单指双击  

        NSLog(@"单指双击");  

    }  

} 

//处理双指事件  

- (void)handleDoubleFingerEvent:(UITapGestureRecognizer *)sender  

{  

    if (sender.numberOfTapsRequired == 1) {  

        //双指单击  

        NSLog(@"双指单击");  

    }else if(sender.numberOfTapsRequired == 2){  

        //双指双击  

        NSLog(@"双指双击");  

    }  

} 

2.手指滑动事件

UISwipeGestureRecognizer *recognizer;  

      

    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  

    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];  

    [[self view] addGestureRecognizer:recognizer]; 

    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  

    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];  

    [[self view] addGestureRecognizer:recognizer];  

    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  

    [recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];  

    [[self view] addGestureRecognizer:recognizer];  

      

    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  

    [recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];  

    [[self view] addGestureRecognizer:recognizer];  

-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer

{  

    if(recognizer.direction==UISwipeGestureRecognizerDirectionLeft||recognizer.direction==UISwipeGestureRecognizerDirectionDown) {

        NSLog(@"swipe left");

        //执行程序

    }

    if(recognizer.direction==UISwipeGestureRecognizerDirectionRight||recognizer.direction == UISwipeGestureRecognizerDirectionUp) {  

        NSLog(@"swipe right");

        //执行程序

    }

}
