NSInternalInconsistencyException - on AppDelegate

Question

My application is crashing with a very weird error message.

The error message is

*** Assertion failure in -[UIStoryboard nibForViewControllerWithIdentifier:], /SourceCache/UIKit_Sim/UIKit-2372/UIStoryboard.m:115
2013-05-06 19:07:04.543 SocialApp[2427:c07] GoogleAnalytics 2.0b3 void GAIUncaughtExceptionHandler(NSException *) (GAIUncaughtExceptionHandler.m:41): Uncaught exception: Invalid parameter not satisfying: [identifier length] > 0

libc++abi.dylib: terminate called throwing an exception

The app was initially crashing at the line

id<GAITracker> tracker = [[GAI sharedInstance] trackerWithTrackingId:googleAnalyticsKey];

but after I commented out the line, it is now crashing at

[window makeKeyAndVisible];

The error message is the same. I have been trying to fix it all day but no solution.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    commonClassInstance = [[Common alloc] init];
    configFileDictionary = [commonClassInstance returnConfigFileDictionary];
    resourceFileDictionary = [commonClassInstance returnResourceFileDictionary];

    //NSString *googleAnalyticsKey = [[configFileDictionary valueForKey:@"Keys"] valueForKey:@"GoogleAnalyticsKey"];

    // Instance to track Uncaught Exception
    [GAI sharedInstance].trackUncaughtExceptions = YES;

    // Optional: set Google Analytics dispatch interval to e.g. 20 seconds.
    [GAI sharedInstance].dispatchInterval = 20;

    // Optional: set debug to YES for extra debugging information.
    [GAI sharedInstance].debug = NO;

    // Create tracker instance.
   // id<GAITracker> tracker = [[GAI sharedInstance] trackerWithTrackingId:googleAnalyticsKey];
//#pragma unused(tracker)

    sleep(3);

    // Override point for customization after application launch.

    [window addSubview:newsViewController.view];
    [window addSubview:blogViewController.view];

    [window addSubview:stocksViewController.view];
    [window addSubview:executiveViewController.view];
    [window addSubview:companyInfoViewController.view];
    [window makeKeyAndVisible];

    return YES;
}

Answer 1

Make sure googleAnalyticsKey is non-nil and has a valid value.

Beyond that, your question doesn't have enough clues. Post the backtrace of the actual crash.
