I'm a complete obj-c newb, so I'll try to be verbose. I have an application originally created with the 4.3 SDK and have had relative ease moving to 5.0, however I am having a new issue. In addition to moving to 5.0, I made the app a universal app and created a new .xib (properly sized) for iPad. I did my best to hook all the pieces together, and it works fine in the simulator for 4.3 and 5.0. However, on the device, the screen is completely blank/white. The app does not crash and I can go back to the preview view and continue with the app as normal. Is there any specific spots I should be looking? Thanks!
