IOS application works during testing, but crashes after release

We just released a new iPhone app using xcode 4.5.2, cordova-2.2.0 During testing, everything worked fine. But after leaving today, it instantly falls. The initial screen flickers for a second, then it falls.

Failure: -iPhone 5 (iOs 6.0.1) -iPhone 4s (iOs 6.0.1) -iPhone 4 (iOs 6.0.1)

BUT! Works with: -iPhone 4 (iOs 5.0)?!?

Since it works on startup with xcode, we cannot reproduce this error, any ideas?

This is a fragment from the crash log, do you need details?

Thanks!

@Antonio Here is the viewDidLoad

It seems that you are calling a method inside viewDidLoad that the CDVViewController cannot handle. It is better to check all the messages that you send to an instance of this class inside this method (most likely, self.property or [self something]).

Make sure you archive and run the application

When you run it in debug mode, you will get a different compilation and possibly a different result. (Debug mode = when you start from Xcode by clicking Run)

In addition, I get the feeling that you are using a method that is deprecated in iOS 6. (Obviously, you get an "undefined selector" error that indicates access to a method that you should not access). that the methods you use are available in iOS 6.

Also, make sure you are not accessing ivars. As far as I know, access to personal ivars is disabled from iOS 6.
