多個手勢似乎沒有工作（* CustomGestureRecognizer和UILongPressGestureRecognizer）

Question

我做了一個自定義的手勢識別器，並將其添加到我的自定義視圖。 自定義手勢是UIPanGestureRecognizer的一個子類。

其他手勢，即時通訊將是LongPressGestureRecognizer

    CustomGestureRecognizer *pan; 
       pan = [[CustomGestureRecognizer alloc] initWithTarget:[self viewController] action:@selector(dragImage:)]; 
       [pan setDirection:DirectionPangestureRecognizerVertical]; 
       [pan setMinimumNumberOfTouches:1]; 
       [pan setMaximumNumberOfTouches:1]; 
       [custom addSubview:custom.imageView]; 
       [custom addGestureRecognizer:pan]; 
       [pan release]; 

       UILongPressGestureRecognizer *highLight = [[UILongPressGestureRecognizer alloc] initWithTarget:[self viewController] 
                          action:@selector(highlightImage:)]; 
       [highLight setDelaysTouchesBegan:0.1]; 
       [tempView addGestureRecognizer:highLight]; 
       [highLight release]; 

而且我已經實現

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer 
{ 
    if (![gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]] && ![otherGestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) 
    { 
     return YES; 
    } 
    return YES; 
} 

兩個IM我的[自我的viewController]，並在自我類，但即時通訊仍然沒有得到兩個手勢工作simultaniiosly。

你忘了設置你的手勢識別器的代表......該方法永遠不會被調用。
