let newView = self.storyboard?.instantiateViewController(withIdentifier: "storyBoardIdentifier") as! PlaceViewController
self.navigationController?.pushViewController(newView, animated: true)

For Storyboards, you should use performSegueWithIdentifierlike so:
对于故事板，您应该performSegueWithIdentifier像这样使用：
[self performSegueWithIdentifier:@"identifier goes here" sender:self];

By default, Xcode creates a standard view controller. we first change the view controller to navigation controller. Select the Simply select “Editor” in the menu and select “Embed in”, followed by “Navigation Controller” Step 1. Select Main story board Step 2.Click on "Editor" on top of your Xcode application. Step 3. Click on "Embed In"
默认情况下，Xcode 创建一个标准的视图控制器。我们首先将视图控制器更改为导航控制器。选择 只需在菜单中选择“Editor”并选择“Embed in”，然后选择“Navigation Controller” Step 1. 选择 Main story board Step 2.单击 Xcode 应用程序顶部的“Editor”。第 3 步。单击“嵌入”
Xcode automatically embeds the View Controller with Navigation Controller.
Xcode 自动将视图控制器嵌入到导航控制器中。
