Apple审批团队的崩溃日志

Question

Apple has rejected my app because it crashes and I can't find a way to know where the problem is. They say that the crash was on an iPhone 4 with iOS6.

I have built the archive with Xcode 4.4 and iOS 5.1. I have already upgrade to Xcode 4.5 and iOS 6. As you will see, Xcode doesn't identify the symbols on every line of the stack trace; in particular, the system function names are missing, maybe due to the update and not the same version on my computer; I don't know.

I'm just unable to reproduce this crash, I don't have an iPhone 4, just a 3GS and have no bugs.

Here is the log:

Can you provide any insight into what's wrong or how to determine what's wrong?

Edit: I think i have found, it was a problem with Game Center and IOS 6. The method "authenticateWithCompletionHandler" is deprecated and make it crash.

Thanks.

Answer 1

1) Your 3GS works fine and its running iOS 6, right?

2) You don't need to switch completely to Xcode4.5 if you don't want to for some reason, just install it side by side with Xcode4.4.1 and just use it to test and run your app in a Retina iPhone simulator.

3) If you still cannot get the crash, then I am going to make a wild guess that this is your problem:

5 UIKit 0x36c54fca -[UIViewController presentViewController:withTransition:completion:] + 3390

Is the presentedViewController retained in a strong variable (if using ARC), or in a retained property in the presenting ViewController? If not make it so, but then, no way to know for sure if it fixes the problem.

A good reason to build up points here is to be able to add a bounty for an answer - I believe 50 points is the min. Assuming you know Android well (given last name, isn't going to make you friends here in iOS land), answer a few question now and get some points.

With a bounty, you maybe can get someone to test your app on their phone by building an Ad Hoc version of the app (but Provisioning H*ll awaits :-( )
