Swift Question

UIControlState,Highlighted only respond from second click/touch

Ive got this line of code that changes the image on a button when clicked:

sender.setImage(UIImage(named: "something.png")!, forState: .Highlighted)

but it never works on the first touch. Can anyone explain to me what I'm doing wrong?

The default image is set in the storyboard.


When you call setImage(_:for:), that is setting the buttons image for the passed in state. You don't have to call it every time the button is tapped. Try call setImage(_:for:) in viewDidLoad, instead of in your IBAction.

The problem is the button has the default highlight state until its first tapped, which is why you are seeing what you are seeing.
