SIGABRT in iOS5

Hello,

I have a problem with the iOS 5 Dolphin App.

I added several views to the app and delegate between them by e.g.

Dolphin6AppDelegate *app = [Dolphin6AppDelegate getApp];
    app.tabController.selectedViewController = app.homeNavigationController;

There is no problem with iOS4.3 but when I run the app on a iOS 5 Simulator or device

I always get a SIGABRT error at this point.

Debugger show an NSException:

int retVal =UIApplicationMain(argc, argv,nil,nil); SIGABRT

objc[3441]: EXCEPTIONS: throwing 0x7d626b0(object0x7d1e750, a NSException)

Does anyone have a clue why this happens?

Thanks in advance.

It maybe that your app.homeNavigationController is not in the view controllers array of the UITabBarController. 

Property selectedViewController can be set to consolers in this array only.

 How can that be if it works in 4.3?

It's better to ask Apple.

It is just suggestion, you can try it if it works.
