I was wondering what some people's opinions are about the best way to test a mapping model? I'm currently working on an app to an upgrade of an app in the app store and want to test the mapping model hard before submitting.
I have been doing exactly this same thing.
I use iPhone Configuration Utility to install the 1.0 version of our app (repeatedly). After that, I simply run the current version of the app (1.0.1) in the debugger in Xcode. Works just fine. HTH
