    Hello, what I am trying to do is display a dot in a view, but I want the color to actively change while in a loop. The problem is that [self setNeedsDisplay:YES] seems to wait until the loop ends before redrawing the view. Is there a way to tell the view to redraw instantly, and not wait for the loop to end first? Any help would be much appreciated.

    Thanks, using display worked. Seems so obvious too. Thanks again.
