首先，我是 Objective C 的新手。我想开发我的第一个应用程序，我想使用 2 个不同的故事板。一款适用于 iPhone 4/4S，一款适用于 iPhone 5 屏幕尺寸。我在如何切换到 iPhone 5 的不同故事板中找到了来自 lionserdar 的非常好的代码？

我的问题是当我将代码添加到我的 AppDelegate.m 时，我遇到了这个问题；

“使用未声明的标识符“InitializeStoryBoardBasedOnScreenSize”

而且我不知道如何解决它。已经谢谢了。

-(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;

   }
}

大写“I”不同于 InitializeStoryBoardBasedOnScreenSize 和 InitializeStoryBoardBasedOnScreenSize？
