Yes, but you need to refactor your code. Just inserting a delay while drawing 
is a bad idea and won't work.

Set up a timer that calls every 0.25 seconds. Each time the timer fires, 
increment an ivar that controls which level of triangle is being drawn, and 
mark the display as needing refresh (-setNeedsDisplay:). Then, in-drawRect:, 
use the 'current triangle' ivar to do the relevant part of the drawing.
