gestureRecognizer：shouldReceiveTouch：没有被调用 [英] gestureRecognizer: shouldReceiveTouch: not getting called

问题描述

gestureRecognizer：shouldReceiveTouch：方法未被调用。我是否设置不正确？

gestureRecognizer:shouldReceiveTouch: method isnt being called. Have i set it up improperly?

-(id) init 
{
UILongPressGestureRecognizer *touchHold = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleTouchHold:)];
touchHold.minimumPressDuration = 1.0f;
touchHold.numberOfTouchesRequired = 1;
[[CCDirector sharedDirector].openGLView addGestureRecognizer:touchHold];
}

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 
{
     return NO;
}

即使我将bool设置为no，仍然会调用按住方法。

Press and hold method is still being called even though i set the bool to no.

推荐答案

好像你还没有设置代理？

Seems like you haven't set the delegate ?

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch

是UIGestureRecognizerDelegate的一部分。所以你也应该设置委托。

Is the part of UIGestureRecognizerDelegate. So you should have set the delegate too.

touchHold.delegate = self;

编辑：
您应该告诉您的视图控制器实现UIGestureRecognizerDelegate。类似

You should tell your view controller to implement the UIGestureRecognizerDelegate. Something like

@interface YourViewController <UIGestureRecognizerDelegate>
