Disable a Button

I want to disable a button (UIButton) on iOS after it is clicked. I am new to developing for iOS but I think the equivalent code on objective - C is this:

button.enabled = NO;

But I couldn't do that on swift.

The boolean value for NO in Swift is false.

button.isEnabled = false

should do it.

Here is the Swift documentation for UIControl's isEnabled property.

If you want the button to stay static without the "pressed" appearance:

// Swift 2
editButton.userInteractionEnabled = false 

// Swift 3
editButton.isUserInteractionEnabled = false 

Remember:

1) Your IBOutlet is --> @IBOutlet weak var editButton: UIButton!

2) Code above goes in viewWillAppear

The way I do this is as follows:

@IBAction func pressButton(sender: AnyObject) {
    var disableMyButton = sender as? UIButton
    disableMyButton.enabled = false
}

The IBAction is connected to your button in the storyboard.

If you have your button setup as an Outlet:

    @IBOutlet weak var myButton: UIButton!

Then you can access the enabled properties by using the . notation on the button name:

    myButton.enabled = false

Disable a button on Swift 3:

yourButton.isEnabled = false
