iOS开发中手势和滑动

1.手指点击事件
[ html]  
//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];  
  
[singleFingerOne release];  
[singleFingerTwo release];  
[doubleFingerOne release];  
[doubleFingerTwo release];  
  
//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
[html] 
UISwipeGestureRecognizer *recognizer;  
      
    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  
      
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];  
    [[self view] addGestureRecognizer:recognizer];  
    [recognizer release];  
    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  
      
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];  
    [[self view] addGestureRecognizer:recognizer];  
    [recognizer release];  
      
    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  
      
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];  
    [[self view] addGestureRecognizer:recognizer];  
    [recognizer release];  
      
      
      
    recognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(handleSwipeFrom:)];  
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];  
    [[self view] addGestureRecognizer:recognizer];  
    [recognizer release];  
 
 
-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer
{
    
    if(recognizer.direction==UISwipeGestureRecognizerDirectionLeft||recognizer.direction==UISwipeGestureRecognizerDirectionDown) {
        
        NSLog(@"swipe left");
        //执行程序
        [self ReadNextPage];
    }
    
    if(recognizer.direction==UISwipeGestureRecognizerDirectionRight||recognizer.direction == UISwipeGestureRecognizerDirectionUp) {
        
        NSLog(@"swipe right");
        //执行程序
        [self ReadLastPage];
    }
    
}
