Well if you have a UIImage and UILabel linked from the Interface Builder, place the following in the viewdidload: method:

// Starting state
myLabel.alpha=0.0;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
// Ending state
myLabel.alpha=1.0;
[UIView commitAnimations];

// Run another function to fade out after a second
[self performSelector:@selector(fadeOut:) withObject:sender afterDelay:1.0];
