Panning / Moving the Line


#1

When I move the line, it flies off the screen. If I go slow I can kind of control it, is this happening to anyone else?

Sounds like your -moveLine: method has a typo in it. Can you go back and double check your code looks exactly like it does in the book? For example, it can be really easy to mix up the "begin"s and "end"s, as well as the "x"s and "y"s.
