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

<

Answer 1

There are two things you need to do:

1. In Storyboard you have mentioned the controller name (eg LoginView) and enable use storyboard ID

2. Then you have user the below line

   loginView = [storyboard instantiateViewControllerWithIdentifier:@"LoginView"];
   [(UINavigationController*)self.window.rootViewController pushViewController:loginView animated:NO];
   

Hope this helps. Let me know if you're still having the issue.

Answer 2

[self performSegueWithIdentifier:@"buyListSegue" sender:sender];

Answer 3

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];
}

Answer 4

I think the controller identifier "CountrySettings" is set to the wrong controller. You're not getting a NavigationController where you can call pushViewController...
