Ios 不同屏幕大小的故事板

如何在Swift中为每个可能的屏幕大小设置不同的故事板

我已经有了Objective-C代码

请不要自动布局，我不需要它

但如何将其转换为Swift？我不熟悉斯威夫特

以下是Objective-C的代码：

AppDelgate.m文件

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    // int screenHeight = [UIScreen mainScreen].bounds.size.height;
    // NSLog(@"Screen Height is %i", screenHeight);

    // grab correct storyboard depending on screen height
    UIStoryboard *storyboard = [self grabStoryboard];

    // display storyboard
    self.window.rootViewController = [storyboard instantiateInitialViewController];
    [self.window makeKeyAndVisible];

    return YES;
}

- (UIStoryboard *)grabStoryboard {
    // determine screen size
    int screenHeight = [UIScreen mainScreen].bounds.size.height;
    UIStoryboard *storyboard;

    switch (screenHeight) {
            // iPhone 4s
        case 480:
            storyboard = [UIStoryboard storyboardWithName:@"Main-4s" bundle:nil];
            break;

            // iPhone 5s
        case 568:
            storyboard = [UIStoryboard storyboardWithName:@"Main-5s" bundle:nil];
            break;

            // iPhone 6
        case 667:
            storyboard = [UIStoryboard storyboardWithName:@"Main-6" bundle:nil];
            break;

            // iPhone 6 Plus
        case 736:
            storyboard = [UIStoryboard storyboardWithName:@"Main-6-Plus" bundle:nil];
            break;

        default:
            // it's an iPad
            storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
            break;
    }
    return storyboard;
}

如果你只是想把代码转换成Swift，你可以参考苹果的Swift教程。你可以在iBook商店或网上查阅这本书。为了便于参考，我把代码转换成了Swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    let splitViewController = self.window!.rootViewController as! UISplitViewController
    let navigationController = splitViewController.viewControllers[splitViewController.viewControllers.count-1] as! UINavigationController
    navigationController.topViewController!.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem()
    splitViewController.delegate = self
    return true


    // int screenHeight = [UIScreen mainScreen].bounds.size.height;
    // NSLog(@"Screen Height is %i", screenHeight);

    // grab correct storyboard depending on screen height

    let storyboard = grabStoryboard()

    // display storyboard
    self.window?.rootViewController = storyboard.instantiateInitialViewController()
    self.window?.makeKeyAndVisible()

    return true
}

func grabStoryboard() -> UIStoryboard
{
    // determine screen size
    let screenHeight = UIScreen.mainScreen().bounds.size.height
    var storyboard: UIStoryboard! = nil

    switch (screenHeight)
    {
    // iPhone 4s
    case 480:
        storyboard = UIStoryboard(name: "Main-4s", bundle: nil)
    // iPhone 5s
    case 568:
        storyboard = UIStoryboard(name: "Main-5s", bundle: nil)
    // iPhone 6
    case 667:
        storyboard = UIStoryboard(name: "Main-6", bundle: nil)
    // iPhone 6 Plus
    case 736:
        storyboard = UIStoryboard(name: "Main-6-Plus", bundle: nil)
    default:
    // it's an iPad
        storyboard = UIStoryboard(name: "Main", bundle: nil)
    }

    return storyboard
}

根据屏幕大小加载不同的故事板：

    // Override point for customization after application launch.
    // int screenHeight = [UIScreen mainScreen].bounds.size.height;
    // NSLog(@"Screen Height is %i", screenHeight);
    // grab correct storyboard depending on screen height
   var storyboard: UIStoryboard = self.grabStoryboard()
    // display storyboard
    self.window.rootViewController = storyboard.instantiateInitialViewController()
    self.window.makeKeyAndVisible()
    return true
}


func grabStoryboard() -> UIStoryboard {
    // determine screen size
    var screenHeight: Int = UIScreen.mainScreen().bounds.size.height
    var storyboard: UIStoryboard
    switch screenHeight {
    // iPhone 4s
    case 480:
        storyboard = UIStoryboard.storyboardWithName("Main-4s", bundle: nil)
    // iPhone 5s
    case 568:
        storyboard = UIStoryboard.storyboardWithName("Main-5s", bundle: nil)
    // iPhone 6
    case 667:
        storyboard = UIStoryboard.storyboardWithName("Main-6", bundle: nil)
    // iPhone 6 Plus

可能重复不重复我不想使用自动布局可能重复不重复我不想使用自动布局我的目标是为每个不同的屏幕大小使用不同的故事板，而不是自动布局，我已经这样做了这是目标c，但不知道如何做这是迅速的。所以你能不能帮我谢谢我的目标是使用不同的故事板为每个不同的屏幕大小，而不是自动布局，我已经做了这是目标c，但不知道如何做这是迅速的。所以你能帮我吗谢谢
