I tried just making the image switch to black and then use sleep(1) and have it go back to the original image, but the sleep doesn't work at the right time, and I can't even see the black flash it goes so fast.

[blueButton setImage:[UIImage imageNamed:@"black.png"] forState:UIControlStateNormal]; sleep(3); [blueButton setImage:[UIImage imageNamed:@"blue.png"] forState:UIControlStateNormal];

I just want to make it give a indicator to this button. Any thoughts? Thanks.
