我在检测UIImageViewself.view 内部的滑动时遇到问题。
当我应用它UISwipeGestureRecognizer时self.view工作正常，但是当我尝试应用它时UIImageview它检测到错误的滑动方向。
代码：
{
//Swipe Up
swipeUpRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeUp:)];
swipeUpRecognizer.delegate = self;
swipeUpRecognizer = (UISwipeGestureRecognizer *)swipeUpRecognizer;
swipeUpRecognizer.numberOfTouchesRequired = 1;
swipeUpRecognizer.direction = UISwipeGestureRecognizerDirectionUp;
[imageView addGestureRecognizer:swipeUpRecognizer];
[swipeUpRecognizer release];
//swipe Down
swipeDownRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeDown:)];
swipeDownRecognizer.delegate = self;
swipeDownRecognizer = (UISwipeGestureRecognizer *)swipeDownRecognizer;
swipeDownRecognizer.numberOfTouchesRequired = 1;
swipeDownRecognizer.direction = UISwipeGestureRecognizerDirectionDown;
[imageView addGestureRecognizer:swipeDownRecognizer];
[swipeDownRecognizer release];
//swipe Left
swipeLeftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeLeft:)];
swipeLeftRecognizer.delegate = self;
swipeLeftRecognizer = (UISwipeGestureRecognizer *)swipeLeftRecognizer;
swipeLeftRecognizer.numberOfTouchesRequired = 1;
swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[imageView addGestureRecognizer:swipeLeftRecognizer];
[swipeLeftRecognizer release];
//swipe Right
swipeRightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeRight:)];
swipeRightRecognizer.delegate = self;
swipeRightRecognizer = (UISwipeGestureRecognizer *)swipeRightRecognizer;
swipeRightRecognizer.numberOfTouchesRequired = 1;
swipeRightRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
[imageView addGestureRecognizer:swipeRightRecognizer];
[swipeRightRecognizer release];
}
