Question

I have a subview thats goes onto the screen animated, and when it is on the screen, I want the superview (in my case, the view in the background), to ignore touch events. I tried everything but it does not work.

是否有办法迫使超级调查停止接收触动事件?

感谢!

When you say the superview, I assume you you mean the animating view s superview. Apple s documentation is very unspecific about userInteractionEnabled, but I think that if you set it to false, it disables touch events on the specific view, but not on its subviews. I would suggest that you do it recursively. Here is an example of code that you could use to disable/enable ALL touch events on a view:

- (void)setInteraction:(BOOL)allow onView:(UIView *)aView {
    [aView setUserInteractionEnabled:allow];
    for (UIView * v in [aView subviews]) {
        [self setInteraction:allow onView:v];
    }
}

然后,请您在座标<代码>上说明这一点。互动:无。当然,这也会使你的触动事件失去意义,因为你正在 rec弃你们的view。当然,你总是能够重新获得你的触动活动<代码>。

另外,Ampap s 。 UIView Level Reference提到,一些ID部件凌驾于这种方法之上:
