jump to a different vew controller on demand

Hello, in my project I have a "sign in" view controller and my root view controller. I want that whenever the user isn't logged in the view will jump to the sign in view controller by a modal segue. I know how to do everything apart from the function to move to the sign in view controller in the viewDidLoad. How do I do that? thanks

in viewDidLoad you will need to check to see if the user is logged in by checking to see if the currentUser variable is not nil. if they are not logged in, call the performSegueWithIdentifier method. make sure your segue is set up as manual segue from your root view controller ro your login view controller in your storyboard

//in your root view controller 
- (void)viewDidLoad {

[super viewDidLoad];

PFUser *currentUser = [PFUser currentUser];

//user is not logged in
if (!currentUser) {

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

}

see 05:59 of this video for more info. it shows how to do exactly what you want
