Question

我的应用中有两个故事板，硬盘为3.5英寸设备，另一个为4英寸设备。我在我的app委托中有这个来检查屏幕的尺寸。

- (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 == 480){
        storyBoard = [UIStoryboard storyboardWithName:@"iphone4.storyboard" bundle:nil];
        UIViewController *initViewController = [storyBoard instantiateInitialViewController];
        [self.window setRootViewController:initViewController];
    }
}

return YES;

}

但由于某些原因，这并没有起作用，所以我决定环顾四周，在一个新的方法中单独使用它，这是，

-(void)initializeStoryBoardBasedOnScreenSize {

if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone)
{
    CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;

    if (iOSDeviceScreenSize.height == 480)
    {

        UIStoryboard *iPhone35Storyboard = [UIStoryboard storyboardWithName:@"iphone4.storyboard" bundle:nil];

        UIViewController *initialViewController = [iPhone35Storyboard instantiateInitialViewController];

        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

        self.window.rootViewController  = initialViewController;

        [self.window makeKeyAndVisible];
    }

    if (iOSDeviceScreenSize.height == 568)
    {

        UIStoryboard *iPhone4Storyboard = [UIStoryboard storyboardWithName:@"Main.storyboard" bundle:nil];

        UIViewController *initialViewController = [iPhone4Storyboard instantiateInitialViewController];

        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

        self.window.rootViewController  = initialViewController;

        [self.window makeKeyAndVisible];
    }

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

{

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

    }
}

我不确定是什么导致它不显示，它只显示4英寸版本，即使我在iphone 4s模拟器中运行它。我忽略了一些超级简单的东西吗？

为什么我的应用程序无法正常显示iphone 4故事板？
