How do I disable a UIButton?
提问by Rahul
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.
我正在做一个项目，我必须在 plist 中显示照片库的所有照片，并在UIButtons 上水平显示它们。
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.
我的应用程序还将有一个编辑按钮：当用户单击此按钮时，每个按钮上应显示一个删除标记（例如通常出现在其他 iPhone/iPad 应用程序中）。
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:
但这里是关键的一点：只要这个删除标记出现，按钮的功能就应该被禁用。我尝试使用以下方法完成此操作：
{
editbutton.enabled=NO;
}
...but it neither produces an error nor works. What should I do?
...但它既不会产生错误也不会起作用。我该怎么办？

In addition to the above:
除上述之外：
Set
editButton.userInteractionEnabled = NO;or you can use
editButton.enabled = NO;
设置
editButton.userInteractionEnabled = NO;或您可以使用
editButton.enabled = NO;
You might want to gray out the button so the user knows it was disabled:
editButton.alpha = 0.66
您可能希望将按钮灰显，以便用户知道它已被禁用：
editButton.alpha = 0.66
