Code before performSegue won't work in a IBAction.

Hi everyone!

I have an UIImageView displaying a "Play" icon in it.

I use a tap gesture recognizer to catch the tap. This gesture recognizer is connected to my HomeViewController with an IBAction.

In prepareForSegue method i prepare some images for the game, so it takes some time like 5 seconds. I want to fade the play button a little, while this time passes. If i manage this i will try to animate the button.

This is my related code:

- (IBAction)beginGame:(id)sender {
    self.playButton.alpha = 0.3f;
    NSLog(@"%f", self.playButton.alpha);
    [self performSegueWithIdentifier:@"beginGame" sender:self];
}

It logs "0.30000", performs the segue but does not change the alpha!

  1. What seems to be the problem?
  2. What do you recommend for time taking segues like this one?

Thanks indeed.
