Are you using storyboards in your project? – spassas Aug 05 '14 at 15:46 — spassas, Aug 05 '14 at 15:46

-(void)terminate{

    MyNewViewController *myNewVC = [[MyNewViewController alloc] init];

    // do any setup you need for myNewVC

    [self presentModalViewController:myNewVC animated:YES];
}

I'm sorry I have been working on this for couple hours straight, how would I setup the new VC? @Pano Katsourakis – Nightmare Aug 05 '14 at 15:30
The setup is only for passing data along to the VC if you have to. – pkatsourakis Aug 05 '14 at 15:33
Actually, I couldn't complete it >.< @Pano Katsourakis – Nightmare Aug 05 '14 at 15:36
Is it cool if you can help me do the setup? @Pano Katsourakis – Nightmare Aug 05 '14 at 15:43

Since your are using storyboards in your project, first make sure that your view controllers have a storyboard identifier. You can set it through the identity inspector in xCode. Then, you can instantiate a new view controller by calling:

YourViewControllerClass *viewController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"ViewControllerId"]; // Replace "MainStoryboard" and "ViewControllerId" with your storyboard name and the storyboard id for your view controller respectively

Then, depending on how your needs you can either push the new view controller (if for example you're using a navigation controller):

[self.navigationController pushViewController:viewController animated:YES];

or present it modally

[self presentViewController:viewController animated:YES completion:nil];

Would I put : `YourViewControllerClass *viewController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"ViewController"];` in the method and also include `[self presentViewController:viewController animated:YES];` @spassas – Nightmare Aug 05 '14 at 16:03
@Sephireth Yes, the first line instantiates your VC, the second presents it. – spassas Aug 05 '14 at 16:06
I get an error on the second line :No visible @interface for 'gameViewController' declares the selector 'presentViewController:animated:' – Nightmare Aug 05 '14 at 16:07
@Sephireth Sorry, my mistake. Try `[self presentViewController:viewController animated:YES completion:nil];`. I edited the answer as well – spassas Aug 05 '14 at 16:11
Now when its executed in-game it crashes the app. I am not sure if I setup Storyboard IDs correctly, I have 3 VC , do I give each the same SB ID or different ones. ? – Nightmare Aug 05 '14 at 16:14
@Sephireth Make sure that your storyboard name, as well as view controller storyboard id and class are set properly. What error do you get? – spassas Aug 05 '14 at 16:16
terminating with uncaught exception of type NSException – Nightmare Aug 05 '14 at 16:17
Check [this question](http://stackoverflow.com/questions/13867565/what-is-a-storyboard-id-and-how-can-i-use-this) for understanding the storyboard IDs – spassas Aug 05 '14 at 16:21
@Sephireth Your identifier is `gameOver` and not `gameOverViewController`. And your storyboard name is wrong, replace it with the filename of your storyboard file without the `.storyboard` extension – spassas Aug 05 '14 at 16:38
