Modal segue, navigation bar disappears

Question

I\'m using Xcode 4.6.1 to code on Objective-C. I want to know how can I keep the navigation bar shown when I create a modal segue between 2 View controllers, because I\'m do

Answer 1

Here is my SHORTED version of "Volodymyr Nazarkevych" in Swift 4.2

 override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    super.prepare(for: segue, sender: sender)
    switch(segue.identifier ?? "") {

    case "segueIdentifier": // name of your segue
        let navigation: UINavigationController = segue.destination as! UINavigationController

        //here you create new name of your destination ViewController and assign his name to let constant above
        guard let myNewViewController = navigation.viewControllers[0] as? DestinationViewController
       //DestinationViewController is your 2-ViewController where you go to from first one.

       else {
            fatalError("Unexpected destination: \(segue.destination)")
        }
       // TO DO SOMETHING HERE

   default:
        fatalError("Unexpected Segue Identifier; \(String(describing: segue.identifier))")
    }
}

The code of "Volodymyr Nazarkevych" works perfectly, but only when your segue is from 1-ViewController to NavigationController of 2-ViewController, not directly to 2-ViewController. THANKS A LOT VOVA!.

Also in switch cases after destination block code you can do different stuff, for example to get some information or file from second ViewController.
