Show ViewController on different Storyboards - ios

Question

I have 3 storyboards for 3 different device screen size. I want to move from the main ViewController to the second ViewController when a button is pressed for the 3 storyboards. Here's the code:
In AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
UIStoryboard *storyBoard;
CGSize result = [[UIScreen mainScreen] bounds].size;
CGFloat scale = [UIScreen mainScreen].scale;
result = CGSizeMake(result.width * scale, result.height * scale);
if(result.height == 1136){
storyBoard = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
UIViewController *initViewController = [storyBoard instantiateInitialViewController];
[self.window setRootViewController:initViewController];
}
else {
storyBoard = [UIStoryboard storyboardWithName:#"Main_iPhone4" bundle:nil];
UIViewController *initViewController = [storyBoard instantiateInitialViewController];
[self.window setRootViewController:initViewController];
}
}
return YES;
}
The code to move to second ViewController:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPhone/Main_iPhone4/Main_iPad" bundle: nil];
ArcadeView *svc = [storyboard instantiateViewControllerWithIdentifier:#"arcade"];
self.window.rootViewController = svc;
However, when i use the above code. XCode tells me
"Could not find a storyboard named
'Main_iPhone/Main_iPhone4/Main_iPad' in bundle NSBundle.
How do i fix this?

Answer 1

Because you don't have a storyboard with name #"Main_iPhone/Main_iPhone4/Main_iPad".
To make it work the way you want, do better in every storyboard make identical transitions and sign them the same identifier.
And for the transitions, use:
[self performSegueWithIdentifier:#"ShowMainMenu" sender:self]
But in general, I advise you to learn more about constraints. So it will be much easier
