I think a more basic question is what you're doing in -drawRect that would generate an exception in the first place. Typically a view should already have access to any relevant resources (strings, images, whatever) before -drawRect is ever called. Assuming that the exception is a reasonable error case and not a bug, it seems like it should be handled in your model and/or controller class and that the view is then configured to display its error "look."
