IOS中关于触屏的方法有专门的类来操作轻扫手势由

UISwipeGestureRecognizer

来实现

关键代码如下

- (void)viewDidLoad {

    [super viewDidLoad];

UISwipeGestureRecognizer *vertical = [[[UISwipeGestureRecognizer alloc] 

  initWithTarget:self action:@selector(reportVerticalSwipe:)] autorelease];

    vertical.direction = UISwipeGestureRecognizerDirectionUp| 

UISwipeGestureRecognizerDirectionDown;

    [self.view addGestureRecognizer:vertical];

    UISwipeGestureRecognizer *horizontal = [[[UISwipeGestureRecognizer alloc] 

initWithTarget:self action:@selector(reportHorizontalSwipe:)] autorelease];

    horizontal.direction = UISwipeGestureRecognizerDirectionLeft| 

UISwipeGestureRecognizerDirectionRight;

    [self.view addGestureRecognizer:horizontal];

}

#pragma mark -

- (void)reportHorizontalSwipe:(UIGestureRecognizer *)recognizer {

NSLog(@"reportHorizontalSwipe");

}

- (void)reportVerticalSwipe:(UIGestureRecognizer *)recognizer {

NSLog(@"reportVerticalSwipe");

}
