iphone - iOS iPhone 5 选择正确的 Storyboard

Question

我正在尝试为我的 iOS 项目使用这两个 Storyboard，但我无法获得切换到适当 Storyboard的代码。相反，代码什么都不做。是我没有正确设置控制开关的设置吗？非 iPhone 5 设备的主 Storyboard称为 MainStoryboard。 iphone 5 合适的布局称为iphone5。我认为这可能是项目配置设置问题。 (这在我的 appdelegate.m 文件中)。

-(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:@"MainStoryboard" 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:@"iphone5" 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;

    }
}

我建议只使用 1 个 Storyboard来处理 iPhone 5 与 iPhone 3-4S 的屏幕尺寸。

当您的 Storyboard 打开时，底部有一个按钮可以在 2 种尺寸之间切换——您可以实时查看事物的外观。

该按钮位于右下角放大 % 缩小按钮的左侧，如下所示:

要处理对象的框架和位置将如何受屏幕尺寸变化的影响——您需要为 View 中的每个对象设置自动调整大小属性。您可以通过选择一个对象来完成此操作，然后在右侧的检查器面板中，选择大小检查器，如下所示:

您看到“自动调整大小”框中的那些红线了吗？与它们一起玩，看看它们将如何影响您的对象。内部的与大小相关(如果宽度或高度拉伸(stretch))，外部的与位置相关。

我不确定您的应用程序布局，但根据经验，您可能不得不弄乱内部垂直线(高度将如何变化)和底线(您希望它保持在底部附近)。

你对每一个的了解越多，你就会越了解每一个的作用。
