1.手指点击事件

//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;

//双指单击

                                                                                  action:@selector(handleDoubleFingerEvent:)];

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

[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

    }
}

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 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
