iPhone didFinishLaunchingWithOptions Method

Question

So i'm trying to use this method to load a certain theme based on what the user chose in the settings bundle. When I insert NSLog it will load the default them (Modern Theme), but it will never change to the Pink Theme.

Is this method loaded every time the app is launched, even if the app is still running in the background.

Otherwise, where else could I do this, if I want to use the settings bundle.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{   
    NSDictionary *userDefaultsDefaults = [NSDictionary dictionaryWithObjectsAndKeys: @"Modern Theme", @"theme", nil];
    [[NSUserDefaults standardUserDefaults] registerDefaults:userDefaultsDefaults];

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    theme =[defaults objectForKey:@"theme"];    

    NSLog(@"%@", theme);

    if ([theme isEqualToString:@"Modern Theme"]) {
        viewController = [[viewTwo alloc] initWithNibName:@"viewTwo" bundle:nil];
    }
    else {
        viewController = [[viewOne alloc] initWithNibName:@"viewOne" bundle:nil];
    }

    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];

    return YES;
}

Have you tried putting your code in applicationDidBecomeActive:? That one is guaranteed to be called whether on the initial launch or resuming from the background.

Reference docs.
