如何禁用 UIButton?

How do I disable a UIButton?(如何禁用 UIButton?)

问题描述

我正在做一个项目，我必须在一个 plist 中显示照片库的所有照片，并在 UIButtons 上水平显示它们.

I am working on a project in which I have to show all photos of Photo Library in a plist and show them horizontally on UIButtons.

我的应用程序也会有一个编辑按钮:当用户单击此按钮时，每个按钮上应该会显示一个删除标记(例如通常出现在其他 iPhone/iPad 应用程序中).

My app will also have an edit button: when the user clicks this button, a delete mark (such as usually appears in other iPhone/iPad apps) should show on each button.

但关键是:一旦这个删除标记出现，按钮的功能应该被禁用.我尝试使用以下方法完成此操作:

But here's the crucial bit: as soon as this delete mark appears, the functionality of the button should be disabled. I've tried accomplishing this with the following:

{
  editbutton.enabled=NO;
}

...但它既不会产生错误也不会起作用.我该怎么办?

...but it neither produces an error nor works. What should I do?

推荐答案

请设置这个...

 editButton.userInteractionEnabled = NO; 

或者你可以使用

 editButton.enabled = NO;
