Can not go back once I start UIViewController

Question

I'm starting a new UIViewController with

let myViewController = MyViewController()
navigationController?.pushViewController(myViewController, animated: true)

But then on my MyViewController() I do not see the arrow to go back, what I'm missing?.

Answer 1

I think that there are 2 solutions to go back.

1. You should use Navigation Controller.
   • Then, make the RootViewController, and connect other ViewController to RootViewController by Seague.
   • Then, pesent the ViewController by performSegue from the current ViewController(RootViewController).

2. You can also implement the back by NavItem.

Answer 2

如果您不在 MyViewController 类中使用 init 方法，请使用故事板标识符加载 MyViewController()。
