调用Superview的UILongPressGestureRecognizer而不是Subview

Question

我有一个奇怪的问题。 我有一个带有customcontrols作为子视图的Superview。 它们是Superview和Subview中的GestureRecognizer。
如果我点击一个子视图，它的GestureRecognizer被调用，而在父视图上，它的水龙头被调用。
但是有时在子视图中长按时会调用超级视图的GestureRecognizer。 我在相同的功能中添加了GestureRecognizers，但态度有所不同。
监督

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapPiece:)];
tapGesture.numberOfTapsRequired = 1;
//contenView is the area where my controls can be
[self.contentView addGestureRecognizer:tapGesture];
[tapGesture release];

UILongPressGestureRecognizer *longTapGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longTapPiece:)];
tapGesture.numberOfTapsRequired = 1;
[self.contentView addGestureRecognizer:longTapGesture];
[longTapGesture release];

子检视

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(selectPiece:)];
tapGesture.numberOfTapsRequired = 1;
[self addGestureRecognizer:tapGesture];

UILongPressGestureRecognizer *longPressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPiece:)];
longPressGesture.numberOfTapsRequired = 1;
[self addGestureRecognizer:longPressGesture];

谁能告诉我为什么长按键不响应我的子视图以及如何解决它。
谢谢

有一个解决方案，但这不是我想要的，我将控件的持续时间设置为低于超级视图之一[longPressGesture setMinimumPressDuration:0.4]; 但是手势识别器应该是独立的
