What is 'self' in the code above? Having the delegate draw the text would be the simplest thing you can do. Next simplest would be to add a CATextLayer sublayer. At a higher level however, you could do the exact same thing with UIViews and use UILabel for your labels (which since they do less work for text layout are generally faster).
