gestureRecognizer：shouldReceiveTouch：没有被调用

Question

gestureRecognizer：shouldReceiveTouch：方法未被调用。我有不正确的设置吗？

-(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。

好像你还没设置代表？

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

是UIGestureRecognizerDelegate的一部分。所以你也应该设置代理。

touchHold.delegate = self;

编辑： 您应该告诉视图控制器实现UIGestureRecognizerDelegate。像

这样的东西

@interface YourViewController <UIGestureRecognizerDelegate>
