Adding a Target to an UIButton

July 28, 2019 ยท 1 minute read

I always seem to forget how to add a target to a button, so that it will automatically run an action or update something immediately. Sometime you just don’t have the brain storage to keep it all in there. So here’s the recipe:

  1. Make sure your button(s) have tags. This make it easier to do different actions for different buttons. Set the tag with code or do it in Storyboard.
fizzButton.tag = 3
  1. Create a method with an @objc so that your button knows what it should do once it is pressed.
@objc func buttonTapped(sender: UIButton)
    if(sender.tag == 3)
        print("hello, fizz") // Do something here for button with tag = 3
  1. Add the addTarget(_:action:for) method on the button in the viewDidLoad() method.
override func viewDidLoad()
    fizzButton.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)

That’s about it.
