Please don't use sleep() on the main thread of a UI application......
If you really want to do this, I'd suggest using an ivar or a static variable
to facilitate going through the operation using
performSelector:withObject:afterDelay:
e.g.:
static int labelLoopCounter = 10;
-(IBAction)buttonPressed
{
if (labelLoopCounter == 10)
{
labelLoopCounter = 0;
[self updateLabel];
}
}
-(void)updateLabel
{
if (labelLoopCounter < 10)
{
label.text = [stringList objectAtIndex:labelLoopCounter];
labelLoopCounter++;
[self performSelector:@selector(updateLabel) withObject:nil
afterDelay:1.0];
}
}
