将UITapGestureRecognizer置于UIButton上方时谁赢了？

Question

我在我的用户界面上放置一个透明的UIView来检测点按手势。我的UI中还有一些UIButton需要保持活动状态。

透明视图下方的UIButton是否会与UITapGestureRecognizer发生冲突？

Answer 1

我尝试了TapRegocnizer的所有选项，这就是结论：

C B E  
       Recognizer and Buttons react
    x  Recognizer and Buttons react
  x    Only Recognizer works
  x x  Only Recognizer works
x      Only Recognizer works
x   x  Only Recognizer works
x x    Only Recognizer works
x x x  Only Recognizer works

Legend:
C: Canceled in View
B: Delayed Begin
D: Delayed End

看起来TapRecognizer总是被触发，即使它下面有一个按钮。如果未设置Canceled in View和Delayed Begin选项，则会激活按钮。因此，要回答我的问题，按钮永远不会超过TapRecognizer。
