目前，我正在使用一个 UI，需要单击按钮，当按钮 alpha 为 1 时，当我将其更改为 0 时，它可以正常工作，但我无法获取按钮触摸事件？ 有什么理由吗？
最佳答案
To hide a view visually, you can either set its hidden property to YES or change its alpha property to 0.0. A hidden view does not receive touch events from the system. However, hidden views do participate in autoresizing and other layout operations associated with the view hierarchy. Thus, hiding a view is often a convenient alternative to removing views from your view hierarchy, especially if you plan to show the views again at some point soon.
