objective-c - how to avoid UIView touch gestures overlapping

Question

I have a UIView on top of another view that's using a UITouchGesture. The problem is that the touch events are being recognised in most forward UIView as well as in the UIView in the background. I would like the touch events to only work on the back most view only.

hope that makes sense.

thanks for any help

Answer 1

view.userInteractionEnabled = NO;

view being the most forward UIview.

Good luck!

Answer 2

我认为最好的方法是在视图中声明 UITouchGesture ，当您需要在视图中禁用触摸时，您可以禁用：

一个水龙头的例子：

在您的 .h 文件中声明它：

UITapGestureRecognizer* tap;

在你的 .m 文件中

tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
[yourView addGestureRecognizer:tap];

当您需要禁用水龙头时，您可以简单：

[tap setEnable:NO];

或删除它：

[yourView removeGestureRecognizer:tap];

这样，当您需要启用/禁用时会更容易，也更容易管理您的触摸。

检查是否[gesture view]等于[[self.view subviews] objectAtIndex:0]并执行任何操作。
