Question

I’d like to display a short warning message in an existing UILabel and then have it automatically disappear after a minute or so without having to pause the app (as in doing a loop or similar).

What’s the best approach ?

Answer 1

Use an NSTimer:

NSTimer* timer = [NSTimer scheduledTimerWithTimeInterval:60 target:self selector:@selector(hideLabel) userInfo:nil repeats:NO]; 

And have a method hideLabel that hides the label, with [myLabel setHidden:YES]; or something like that.
