未调用UISwipeGestureRecognizer方法？

Question

在我的Box2d游戏中，我尝试使用uiswipegesture来获取滑动手势，当我在测试项目中它工作正常但是当我在box2d游戏中实现它不会在这里调用滑动动作是代码

{UISwipeGestureRecognizer *swipeGestureup = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerSwipeUp)];
    [swipeGestureup setDirection: UISwipeGestureRecognizerDirectionUp ];



    [[[CCDirector sharedDirector] openGLView] addGestureRecognizer:swipeGestureup];

    [swipeGestureup release];}

和方法是

-(void)oneFingerSwipeUp:(id)sender{

NSLog(@"swipe auction called");

[player jump];

}

Answer 1

{
  UISwipeGestureRecognizer *swipeGestureup = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(oneFingerSwipeUp:)];
  [swipeGestureup setDirection: UISwipeGestureRecognizerDirectionUp ];

  [[[CCDirector sharedDirector] openGLView] addGestureRecognizer:swipeGestureup];

  [swipeGestureup release];
 }

- (void)oneFingerSwipeUp:(UISwipeGestureRecognizer *)recognizer{
  NSLog(@"swipe auction called");

  }
