iOS設(shè)備的手勢操作船侧，在app中是個必須且實用的功能，為app加分不少厅各。

向左向右輕劃

UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self  action:@selector(handleSwipeLeft)];  
swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;  
[self.view addGestureRecognizer:swipeLeft];  
[swipeLeft release];  
UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc]   
                                         initWithTarget:self   
                                                 action:@selector(handleSwipeRight)];  
swipeRight.direction = UISwipeGestureRecognizerDirectionRight;  
[self.view addGestureRecognizer:swipeRight];  
[swipeRight release];  

單指單擊

UITapGestureRecognizer *singleFingerOne = [[UITapGestureRecognizer alloc] initWithTarget:self   
                  action:@selector(handleSingleFingerEvent:)];  
singleFingerOne.numberOfTouchesRequired = 1; //手指數(shù)  
singleFingerOne.numberOfTapsRequired = 1; //tap次數(shù)  
singleFingerOne.delegate = self;  
[self.view addGestureRecognizer:singleFingerOne];  

單指雙擊

UITapGestureRecognizer *singleFingerTwo = [[UITapGestureRecognizer alloc] initWithTarget:self   action:@selector(handleSingleFingerEvent:)];  
singleFingerTwo.numberOfTouchesRequired = 1;  
singleFingerTwo.numberOfTapsRequired = 2;  
singleFingerTwo.delegate = self;  
[self.view addGestureRecognizer:singleFingerTwo];  

雙指單擊和雙擊

 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;  
[self.view addGestureRecognizer:doubleFingerOne];  
[self.view addGestureRecognizer:doubleFingerTwo];  

//如果不加下面的話镜撩，當(dāng)單指雙擊時队塘，會先調(diào)用單指單擊中的處理，再調(diào)用單指雙擊中的處理  
[singleFingerOne requireGestureRecognizerToFail:singleFingerTwo];  
//同理雙指亦是如此  
[doubleFingerOne requireGestureRecognizerToFail:doubleFingerTwo];  

事件處理方法：

 - (void)handleSingleFingerEvent:(UITapGestureRecognizer *)sender  
 {  
    if (sender.numberOfTapsRequired == 1) {  
        //單指單擊  
        NSLog(@"單指單擊");  
    }else if(sender.numberOfTapsRequired == 2){  
        //單指雙擊  
        NSLog(@"單指雙擊");  
     }  
 }  
 //處理雙指事件  
 - (void)handleDoubleFingerEvent:(UITapGestureRecognizer *)sender  
 {  
    if (sender.numberOfTapsRequired == 1) {  
         //雙指單擊  
         NSLog(@"雙指單擊");  
     }else if(sender.numberOfTapsRequired == 2){  
         //雙指雙擊  
         NSLog(@"雙指雙擊");  
     }  
}
