为手动 Segue 实施 3D Touch "Peek and Pop"

Question

我正在尝试弄清楚如何为我正在处理的应用程序实现 "Peek and Pop" 3D 触摸功能，但我不确定如何为手动转场实现该功能，所以任何帮助或文件将不胜感激。

为了向您提供更多信息，我有一个 UITableView 谁的控制器有 2 个手动 segue，我的代码根据用户点击的 table 元素在它们之间进行选择。如果它是我从原型 table 单元格拖到目标视图控制器的一个 segue，我可以选中一个框，但是手动 segues 不存在该框。

我用谷歌搜索了一下是否有这方面的文档，但我找不到任何东西。

根据 UIViewControllerPreviewingDelegate Reference，实施

func previewingContext(_ previewingContext: UIViewControllerPreviewing,
  commitViewController viewControllerToCommit: UIViewController)

Implement this method to configure and present the commit (pop) view controller, in a way that is appropriate for your app.

For example, to present the commit view controller’s view in a navigation controller, call the navigation controller’s showViewController:sender: method; to present the view modally, you could call the presentViewController:animated:completion: method.

所以在你的实现中你可以说：

func previewingContext(previewingContext: UIViewControllerPreviewing,
      commitViewController viewControllerToCommit: UIViewController){
      self.navigationController.showViewController(viewControllerToCommit,sender:self)
}

或

func previewingContext(previewingContext: UIViewControllerPreviewing,
      commitViewController viewControllerToCommit: UIViewController){
      self.navigationController.pushViewController(viewControllerToCommit,animated:true)
}

如果您对此更满意。
