How can I load different storyboards depending on the device?

Question

I am trying to:

1. detect device (iPhone 3.5", iPhone 4", iPad, ect)
2. load a different storyboard depending on what device and what size the application is running on.

I have watched some tutorials but I am still not getting it, can someone please type/show what code needs to go in the app delegate to achieve these goals.

Thanks!

Try something like this in your app delegate:

- (void)applicationDidFinishLaunching:(UIApplication *)application {
    UIStoryboard *storyboard = nil;
    if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone)
    {
        if ([[UIScreen mainScreen] bounds].size.height == 568.0f)
        {
            storyboard = [UIStoryboard storyboardWithName:@"iPhone5s" bundle:nil];
        }
        else
        {
            storyboard = [UIStoryboard storyboardWithName:@"iPhone4" bundle:nil];
        }
    }  
    else
    {
        storyboard = [UIStoryboard storyboardWithName:@"iPad" bundle:nil];
    }
    [window setRootViewController:[storyboard instantiateInitialViewController]];
    [window makeKeyAndVisible];
}
