How can I disable a button in Xcode?

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

If you are looking for a Swift 3.0 solution:

button.isEnabled = false
