Swift 3 如何模态呈现splitview控制器？

Question

您好，我正在尝试从 UiViewController 展示 UiSplitViewController。我在 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

None 以上方法都有效我该如何解决这个问题。谢谢。

Answer 1

let 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
