Xcode deployment target

If my deployment target is set to iOS 4.1 and submitted to apple, and they test the app on iOS 4.3, woul开发者_JAVA技巧d that cause the app to malfunction? My app was rejected for a bug that I am unable to recreate on my iPhone 4. The exact same device model they tested the app on. I simply cannot find the bug or error in my code. Any advice would be greatly appreciated.

If you build your app to target iOS 4.1 it should run on iOS 4.3. It's possible that your app does something that works on 4.1 but causes a problem on 4.3; I had that myself with an app already in the store, and had to post an update so it worked correctly under a newer iOS release.

Note that you can tell the iOS Simulator what version iOS to simulate: on the Hardware menu, select Version, and subsequent runs will be tested against that version of the system libraries.

The simulator is not a perfect reproduction of a real device, but hopefully you can do this to reproduce the behavior that Apple has seen on their devices.

Did you test it on your iPhone 4 with iOS 4.3? There's two parts to the puzzle. If they rejected it for crashing under iPhone 4, you have to check all the different iOS versions you claim to support. The target iOS 4.1 should still make it work on 4.3, you just might have a crash (which apparently you do). Through testing with that actual software version on your iPhone, you'll find the bug and hopefully squash it. Good luck!
