如何在Xcode中禁用按钮？

Question

I am new to iPhone development. I am building an app by using Xcode but now would like to disable a button. How is this possible?

Answer 1

myButton.enabled = NO;

Answer 2

Via code:

myButton.enabled = NO;

If you're using interface builder there's an "enabled" option.

Answer 3

如果您正在寻找Swift 3.0解决方案：

button.isEnabled = false

Answer 4

button.enabled = NO;

you can set the button property to no and if interface builder you can uncheck the property

Answer 5

 button.enabled = true; 

this will ENABLE the button

button.enabled = false;

this will DISABLE the button. If you want to hide the button you can do this

button.alpha = 0.0;

and if you want to show the button once more you can do this.

button.alpha = 1.0

Hope this helps! :)
