How twitter ios app is doing to push the profile page with a new UINavigationController

Question

I wondering how Twiter is doing, in the ios app, to push a profile viewController with a new navbar or a new navigationController above the current viewController ?

Answer 1

In your stoyboard you have your UITabBarController connected to the UIUserController. Embed a UINavigationController between them and you get the desired result.

Answer 2

The UINavigationController is probably the same. What seems to be a custom navigation bar is actually a transparent navigation bar and a UIView coming from the top behind it.

Answer 3

You will need to hide the Navigation bar in viewWillAppear and show it for the pushed view controller

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)
    self.navigationController?.setNavigationBarHidden(true, animated: true)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(true)
    self.navigationController?.setNavigationBarHidden(false, animated: true)
}
