UIView Drawing Model

-[UIView setNeedsDisplay]

You have some kind of custom UIView which implements some awesome drawing in -[UIView drawRect:]. In order to have UIKit draw it for you, you send the -[UIView setNeedsDisplay] to the view object to queue it up for drawing.

-[CALayer setNeedsDisplay]

CGRectDivide is handy for slicing up a rectangle.

Example of getting a slice and the remaining area of a rectange.

CGRect rect = CGRectMake(0, 0, 240, 150);
  
CGRect remainder, slice;
    
CGRectDivide(rect, &slice, &remainder, 120, CGRectMinYEdge);
