调用 Superview 的 UILongPressGestureRecognizer 而不是 Subview
我遇到了一个奇怪的问题。我有一个超级视图,其中自定义控件作为子视图。 它们在超级视图和子视图中都是 GestureRecognizer。
如果我点击子视图,它的 GestureRecognizer 会被调用,而在超级视图上点击,它的点击会被调用。
但在子视图中长按时,有时会调用超级视图的 GestureRecognizer。我在相同的函数中添加了 GestureRecognizers,但态度不同。
超级视图
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];
子视图
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不响应我的子视图以及如何修复它。
谢谢
i got a strange problem. I got a Superview with customcontrols as subviews.
Their are GestureRecognizer both in superview and subviews.
If i tap a subview its GestureRecognizer gets called and on tap on the superview its tap gets called.
but on long press in the subview SOMETIMES the GestureRecognizer of the superview gets called. I add the GestureRecognizers in the same functions but there is a different attitude.
Superview
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];
Subviews
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];
Can anyone tell me why the longtap doen't response to my subview and how to fix it.
THANK YOU

得到了一个解决方案,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的持续时间
[longPressGesture setMinimumPressDuration:0.4];
但是gestureRecognizer应该是独立的got a solution but this is not what i wanted i set the duration of the control lower than the one of the superview
[longPressGesture setMinimumPressDuration:0.4];
But the gestureRecognizer should be independend
