UITabBarController setting selected index on launch causing issues

Question

I have 5 tabs and on applicationWillTerminate the currently selected index is archived for use on the next launch. I am having some issues with setting the selected index when the application launches the next time. It seems that if I use the following it works, albeit quite hackishly (it displays tab 1 for a split second then goes to the proper tab):
[self performSelector:@selector(selectSavedTabBarIndex) withObject:nil afterDelay:0.0];
If I do either of the following it works great on the simulator but locks up the device requiring pressing the power button and waiting 10 seconds to close the app. There are no errors/crashlogs of the event when hooked up to a debugger.
[self selectSavedTabBarIndex];
// Add the tab bar controller's current view as a subview of the window
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
// Add the tab bar controller's current view as a subview of the window
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
[self selectSavedTabBarIndex];
Does anyone have any ideas why this would occur? Could it be an Apple bug?

Answer 1

Maybe i'm not understanding something the problem. The app i'm working on has a tab bar controller, so it was pretty easy for me to select which tab view is shown initially like this:
- (void)applicationDidFinishLaunching:(UIApplication *)application
     self.playNetwork = [[NSUserDefaults standardUserDefaults] stringForKey:@"network_mode_preference"];
     self.user = [[NSUserDefaults standardUserDefaults] stringForKey:@"user"];
     // Create the navigation and view controllers
     [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
     MZAppDelegate *appDelegate = (MZAppDelegate *)[[UIApplication sharedApplication] delegate];
    appDelegate.channelList = [NSMutableArray array];
    appDelegate.contentList = [NSMutableArray array];
     appDelegate.messagesList = [NSMutableArray array];
     UITabBarController *aTabBarController = [[UITabBarController alloc] init];
     firstViewController = [[FirstViewController alloc] init];
     secondViewController = [[SecondViewController alloc] init];
     thirdViewController = [[ThirdViewController alloc] init];
     fourthViewController = [[FourthViewController alloc] init];
     fifthViewController = [[FifthViewController alloc] init];
     aTabBarController.delegate = self;
     self.tabBarController = aTabBarController;
     NSArray *tabViewControllers = [[NSArray alloc] initWithObjects:firstViewController,
                                                                                   secondViewController,
                                                                                   thirdViewController,
                                                                                   fourthViewController,
                                                                                   fifthViewController,
                                                                                   nil];
     [tabBarController setViewControllers: tabViewControllers animated:YES];
     tabBarController.selectedIndex = 4;
     [tabBarController release];
     [tabViewControllers release];
     [firstViewController release];
     [secondViewController release];
     [thirdViewController release];
     [fourthViewController release];
     [fifthViewController release];
     // Configure and show the window
    [window addSubview:[tabBarController view]];
... is this not what you're also trying to do?
