Superview的UILongPressGestureRecognizer被调用而不是Subview
我遇到了一个奇怪的问题。我将自定义控件作为子视图获得了Superview。
他们是超级视图和子视图中的GestureRecognizer。
如果我点击一个子视图，它的GestureRecognizer会被调用，并且在超级视图上点击它的点击被调用。
但是在子视图中长按，有时会调用superview的GestureRecognizer。我在相同的功能中添加了GestureRecognizers，但是态度不同。

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];
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];

但是gestureRecognizer应该是独立的
