iphone中的手勢識別器疑惑

Question

我知道在ios中處理手勢，但是可以爲動作實現DoubleTapGesture嗎？ 這意味着

UISwipeGestureRecognizer *swipeGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGesture:)]; 
    swipeGesture.direction = UISwipeGestureRecognizerDirectionRight; // or whatever 
    [table addGestureRecognizer:swipeGesture]; 
    [swipeGesture release]; 
    UISwipeGestureRecognizer *swipeGestureleft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeGestureleft:)]; 
    swipeGestureleft.direction = UISwipeGestureRecognizerDirectionLeft; // or whatever 
    [table addGestureRecognizer:swipeGestureleft]; 
    [swipeGestureleft release]; 

我們可以通過這種方式做左，右輕掃，但我想DoubleTap姿態不喜歡上面的代碼中的作用。 在此先感謝。

您可以爲配置UITapGestureRecognizer：

UITapGestureRecognizer *dblTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)]; 
dblTap. numberOfTapsRequired = 2; 
[table addGestureRecognizer:dblTap]; 
[dblTap release];
