我需要执行哪些步骤？在 Objective-C 中，我们创建了 rootViewController 和 detailViewController，之后将这些控制器添加到 splitViewController。例如：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor whiteColor];
    UISplitViewController *splitViewController = [[UISplitViewController alloc] init];
    MTTRootViewController *rootViewController = [[MTTRootViewController alloc] init];
    MTTDetailedViewController *detailedViewController = [[MTTDetailedViewController alloc]init];
    splitViewController.viewControllers = [NSArray arrayWithObjects:rootViewController, detailedViewController, nil];
    [self.window setRootViewController:(UIViewController*)splitViewController];
    [self.window makeKeyAndVisible];
    return YES;
}

如何在 Swift 中做同样的事情？

【解决方案1】：

如果你想用 navigationController 来做，那就试试吧：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window!.backgroundColor = UIColor.whiteColor()
    var splitViewController =  UISplitViewController()
    var rootViewController = RootViewController()
    var detailViewController = DetailViewController()
    var rootNavigationController = UINavigationController(rootViewController:rootViewController)
    var detailNavigationController = UINavigationController(rootViewController:detailViewController)
    splitViewController.viewControllers = [rootNavigationController,detailNavigationController]
    self.window!.rootViewController = splitViewController
    self.window!.makeKeyAndVisible()
    return true
}

一段时间后我找到了答案：

第一次需要创建rootViewController和detailViewController。例如，rootViewController 将继承自 UITableViewController，detailViewController 将继承自 UIViewController。下次你需要这样做：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        self.window!.backgroundColor = UIColor.whiteColor()
        var splitViewController =  UISplitViewController()
        var rootViewController = RootViewController()
        var detailViewController = DetailViewController()
        splitViewController.viewControllers = [rootViewController,detailViewController]
        self.window!.rootViewController = splitViewController
        self.window!.makeKeyAndVisible()
        return true
    }
