Quality is delighting customers
What exactly do you need to test? an application running on iPad or the iPad itself? If its an application, then a software is a software, you test it according to its requirements and needs. There is no such thing as test cases for iPad application, there is always an application that is compatible with iPad and iOS, it will have certain characteristics, features, requirements and design. Analyse all that and think of the scenarios you can test, like what it does, what it should/shouldn't do, what it was suppose to do but isn't doing, etc...
Like I said understand the requirements of the application.
Ask questions like;
And any other question that can help you understand the overall scenario. Then figure out different conditions and cases for testing it. Because unless and until you know what the product is you will not be able to test it.
