CGContextSelectFont CGContextSetRGBFillColor CGContextShowTextAtPoint and on and on, which is horribly low level. 2) using NSString drawAtPoint (so far the method I like) NSString* text = @"Hello"...

Hi, I have a scenario that I'm not sure whether to retain a view controller or not. Say I had ViewControllerOne. When a button was pressed, ViewControllerOne would push ViewControllerTwo in the navigation stack.
