I am trying to change the image of a UIButton using Swift... What should I do
This is OBJ-C code.but I don't know with Swift:
[playButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];
From your Obc-C code I think you want to set an Image for button so try this way:
let playButton = UIButton(type: .Custom)
if let image = UIImage(named: "play.png") {
playButton.setImage(image, forState: .Normal)
}
In Short:
playButton.setImage(UIImage(named: "play.png"), forState: UIControlState.Normal)
For Swift 3:
let playButton = UIButton(type: .custom)
playButton.setImage(UIImage(named: "play.png"), for: .normal)
