UIView——“启用用户交互"对父母是假的，但对孩子是真的? [英] UIView -- "user interaction enabled" false on parent but true on child?

问题描述

父视图上的 userInteractionEnabled=NO 似乎会阻止用户在所有子视图上进行交互.这个对吗?有没有办法解决这个问题?

It appears that userInteractionEnabled=NO on a parent view will prevent user interaction on all subviews. Is this correct? Is there any way around this?

推荐答案

没错，在父视图上将 userInteractionEnabled 设置为 NO 将向下级联到所有子视图.如果您需要某些子视图启用交互，而不是其他，您可以将子视图分成两个父视图:一个 userInteractionEnabled = YES，另一个 NO.然后将这两个父视图放在主视图中.

That's correct, userInteractionEnabled set to NO on a parent view will cascade down to all subviews. If you need some subviews to have interaction enabled, but not others, you can separate your subviews into two parent views: one with userInteractionEnabled = YES and the other NO. Then put those two parent views in the main view.
