Instantiating a View Controller programmatically with Storyboard from AppDelegate

Question

I\'m busy building an app - that when launched for the first time it asks the user to do two things:

1. Select a Country
2. Accept T&Cs

You're expecting the self.window.rootViewController to be a UINavigationController but it's a UIViewController. This means that the outermost view controller in your storyboard is of the wrong type.

A better way to obtain the UINavigationController (Which should work in this case) is to use the property self.navigationController on any UIViewController.

From what I understand you want to present a view the first time the user runs to have the user pick some stuff. What you should then do is present a modal view controller, like this:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//isFirstRun is some boolean you use to determine if it's the first run
if(isFirstRun){
    BBCounterySettingsViewController *controller = (BBCounterySettingsViewController *)[mainStoryboard instantiateViewControllerWithIdentifier: @"CountrySettings"];
    [self.window.rootViewController presentViewController: controller animated:YES completion:nil];
}
