swift3 - Swift 3 如何以模态方式呈现 splitview 控制器？

Question

嗨，我正在尝试从 UiViewController 展示 UiSplitViewController。我正在 UiViewController 中进行一些搜索，并根据结果显示 UiSplitViewController。我怎样才能以编程方式做到这一点？到目前为止，我在谷歌搜索后尝试了 3 种方法

1.self.performSegue(withIdentifier: "SearchComplete", sender: self)

2.self.present(PrimarySplitViewController(), animated: true, completion: nil)

3.let detailViewController = self.storyboard?.instantiateViewController(withIdentifier: "SplitView") as! UISplitViewController self.splitViewController?.viewControllers[1] = detailViewController

以上方法均无效，我该如何解决。谢谢你。

Answer 1

让 mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

    let viewController = mainStoryboard.instantiateViewController(withIdentifier: "SplitView") as! UISplitViewController

    UIApplication.shared.keyWindow?.rootViewController = viewController 

您必须设置根视图控制器
