-- It is my button frame. Where *** - it is working. Where empty place doesn't work.

Thanks for your help.

Answer 1

为按钮添加背景色，并检查按钮的放置方式和位置。如果按钮位于自定义视图之外，则无法对该外部部分执行操作。

Answer 2

Check that your button frame lies inside the parent's frame. Area of button outside Parent's frame freezes and doesn't respond to touch events. Set clipToBounds = YES; on button to test it.
