I’d like to create a simple fingerpainting feature in my app. Problem is any drawings I do to my UIView subclass view instance are erased after each drawRect call… How do you go about preserving your context drawings in your UIViews?

You have to add your drawings to your model and make sure your model is rendered, as appropriate, when the view is invalidated. You do not want to be drawing on the view directly without a model around to re-render it when necessary.
