Question

我正试图在app delegate中启动时在两个故事板之间做出决定。首先，我删除了Info.plist中的NSMainStoryboardFile = Main条目，以防止自动加载Storyboard。

然后我尝试从AppDelegate加载主故事板，但这不起作用。

<section class="artistpage">
    <ul class="artistlist" ng-app>
        <li ng-animate="animate'" class="artist cf" ng-repeat="lec in lecture | orderBy: videoId">
                <div class="info">
                    <h2>{{lec.videoName}}</h2>
                    <h3>{{lec.videoDetails | cut:true:160:' ...'}}</h3>
                </div>
        </li>
    </ul>
</section>

我不确定为什么。希望有人可以提供帮助。

Answer 1

var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    window=UIWindow(frame: UIScreen.mainScreen().bounds)

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let navigationController:UINavigationController = storyboard.instantiateInitialViewController() as! UINavigationController
    var rootViewController:UIViewController = storyboard.instantiateViewControllerWithIdentifier("LoginView") // LoginView is your view controller name

    navigationController.viewControllers = [rootViewController]
    self.window?.rootViewController = navigationController
    self.window?.makeKeyAndVisible()
    window?.backgroundColor=UIColor.blackColor()

    return true
}

Answer 2

这应该完美无缺 -

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)

    var sb = UIStoryboard(name: "Main", bundle: nil)
    var initialVC = storyboard.instantiateInitialViewController() as! UIViewController

    self.window?.rootViewController = initialViewController
    self.window?.makeKeyAndVisible()
    return true
}
