UIViewAnimationOptionAllowUserInteraction 是否应用于动画视图或整个屏幕？

Question

根据文档，此调用

[UIView animateWithDuration:0.3 animations:^{
    someView.alpha = 1.0;
}];

等同于

 [UIView animateWithDuration:0.3 delay:0.0 options:0 animations:^{
     someView.alpha = 1.0;
 } completion:nil];

– 因此不传递 UIViewAnimationOptionAllowUserInteraction 选项。如果不添加此选项会怎样？

动画中的所有视图（在此示例中 someView）是否都不会收到任何用户交互或它是否适用于整个屏幕？

我在文档中找到的是

UIViewAnimationOptionAllowUserInteraction
Allow the user to interact with views while they are being animated.

Answer 1

它只影响动画视图。不是整个屏幕。

Does UIViewAnimationOptionAllowUserInteraction be applied to the views animated or the whole screen?
