Discussion of [UITextField drawPlaceholderInRect]
You should not call this method directly. If you want to customize the drawing behavior for the placeholder text, you can override this method to do your drawing.

By the time this method is called, the current graphics context is already configured with the default environment and text color for drawing. In your overridden method, you can configure the current context further and then invoke super to do the actual drawing or do the drawing yourself. If you do render the text yourself, you should not invoke super.
