まず第一に、私は Objective C の初心者です。最初のアプリを開発したかったのですが、2 つの異なるストーリーボードを使用したいと考えています。1 つは iPhone 4/4S 用、もう 1 つは iPhone 5 の画面サイズ用です。How to switch to different Storyboard for iPhone 5?で lionserdar からの本当に素敵なコードを見つけました。

私の問題は、コードを AppDelegate.m に追加するときです。この問題が発生しています。

"宣言されていない識別子 "InitializeStoryBoardBasedOnScreenSize" の使用

そして、私はそれを修正する方法がわかりません。もうありがとう。

-(void)initializeStoryBoardBasedOnScreenSize {
    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone) { // The iOS device = iPhone or iPod Touch

        CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;

        if (iOSDeviceScreenSize.height == 480)
        {   // iPhone 3GS, 4, and 4S and iPod Touch 3rd and 4th generation: 3.5 inch screen (diagonally measured)

            // Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone35
            UIStoryboard *iPhone35Storyboard = [UIStoryboard storyboardWithName:@"Storyboard_iPhone35" bundle:nil];

            // Instantiate the initial view controller object from the storyboard
            UIViewController *initialViewController = [iPhone35Storyboard instantiateInitialViewController];

            // Instantiate a UIWindow object and initialize it with the screen size of the iOS device
            self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

            // Set the initial view controller to be the root view controller of the window object
            self.window.rootViewController  = initialViewController;

            // Set the window object to be the key window and show it
            [self.window makeKeyAndVisible];
       }

       if (iOSDeviceScreenSize.height == 568)
       {   // iPhone 5 and iPod Touch 5th generation: 4 inch screen (diagonally measured)

           // Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone4
           UIStoryboard *iPhone4Storyboard = [UIStoryboard storyboardWithName:@"Storyboard_iPhone4" bundle:nil];

           // Instantiate the initial view controller object from the storyboard
           UIViewController *initialViewController = [iPhone4Storyboard instantiateInitialViewController];

           // Instantiate a UIWindow object and initialize it with the screen size of the iOS device
           self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

           // Set the initial view controller to be the root view controller of the window object
           self.window.rootViewController  = initialViewController;

           // Set the window object to be the key window and show it
           [self.window makeKeyAndVisible];
       }

   } else if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad)

   {   // The iOS device = iPad

       UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
       UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
       splitViewController.delegate = (id)navigationController.topViewController;

   }
}

大文字の「I」は、initializeStoryBoardBasedOnScreenSize と InitializeStoryBoardBasedOnScreenSize が異なりますか?
