制作适用于兼容3.5英寸4英寸显示屏的iPhone应用程序

Question

我的应用程序设计时只考虑了4英寸显示屏。在3.5英寸模拟器上运行时，应用程序缺失.5英寸。

我的问题是，我如何在Xcode 5中为不同的屏幕尺寸设置不同的故事板？

我知道在使用以下代码之前：

-(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 *Main_iPhone2 = [UIStoryboard storyboardWithName:@"Main_iPhone3" bundle:nil];

        // Instantiate the initial view controller object from the storyboard
        UIViewController *initialViewController = [Main_iPhone2 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 *Main_iPhone = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];

        // Instantiate the initial view controller object from the storyboard
        UIViewController *initialViewController = [Main_iPhone 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;

}

}

但与Xcode 5的交易，以及我认为此代码无效的原因是项目中的“常规”下有一个部分，它在整个特定设备类型中建立故事板作为主要故事板。

所以，要么采用不同的方式来完成整个单独的故事板，要么就是我对代码做错了。该代码被放置在我的应用程序委托中，所以不要认为我有任何错误。

Answer 1

在Xcode 5 - Storyboard中找到此控件。左边的按钮在整个故事板中切换3.5到4英寸的视图。希望这是你需要的。

Answer 2

尝试根据您的控件和视图设置自动调整左，右，底，顶部位置，
