When I try to do Play.hidden = true , I get the error message "fatal error: unexpectedly found nil while unwrapping an Optional value". My button outlets are connected.
Here's my code(inside of viewController class) :
@IBOutlet weak var Play: UIButton!
@IBOutlet weak var Stop: UIButton!
Here's my method:
@IBAction func recordButton(sender: AnyObject) {
Play.hidden = true
}
Here's another screenshot:
Any suggestions would help. Thank you!
Thanks guys for all your suggestions . I just disconnected the play button outlet and connected it again(Credit to @HAS).[I also renamed the Outlet from "Play" to "playButton" because I have a variable var play = AVAudioPlayer() .
I'm not sure what the reason was but it is now fixed.
