You would probably have to use a fixed width font and calculate if it's too large for the screen. Actually, there might be functions that do this...google around.

That kind of thing, right?

If this is in a tableview, then I think you'll be challenged. As I understand that each time you make a change, you have to redraw the cells all over again.

Use a UIScrollView and programmatically (in a loop or via a timer) set your contentOffset.

Write your own UIView Subclass. Set up a timer to setNeedsDisplay the view. Have it draw its text in its drawRect based on a position. Move the position to the left on each iteration of the timer. Double the text so it automatically draws the start of the text after the end of the text. Figure out when you need to restart the text from the beginning.
