I'm just practising with views and animations.

Generally, you don't call -lockFocus on a view unless you have a very good reason. As you've already found out, -lockFocus will raise exceptions if things aren't set exactly right. Instead, you do all your drawing in -drawRect:, and call -setNeedsDisplay: & friends when you need to refresh part of the view.
