在启动时为UISplitViewController

Question

我有一个用于rootViewController的UISplitViewController！

我不知道如何为动画启动画面呈现UIViewController！

在AppDelegate.swift中我有：

class AppDelegate: UIResponder, UIApplicationDelegate, UISplitViewControllerDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    let splitViewController = window!.rootViewController as! UISplitViewController

    splitViewController.preferredDisplayMode = .allVisible
    splitViewController.preferredPrimaryColumnWidthFraction = 1.0
    splitViewController.maximumPrimaryColumnWidth = 360

    splitViewController.delegate = self

    return true
} ...

我在哪里以及如何在UISplitViewController上“全屏”呈现UIViewController？

Answer 1

在您可以调用SplitViewController的ViewController中：

let newVc = ViewController() //change this to your class name
self.splitViewController?.presentViewController(vc, animated: true, completion: nil)

Answer 2

您可以将ViewController设置为rootViewController for window，以全屏模式显示它。之后，您可以将SplitViewController转回窗口。
