Ios – Navigation Bar not selectable in Show Segue, Xcode 6.1

iosiphonexcodexcode6

There are 2 View Controllers in my storyboard, VC_A and VC_B

I have embeded a navigation controller in VC_A which is a Table View Controller, I then control drag the Prototype Cell into VC_B to create a segue. If I select "show" in "selection segue" then in VC_B I can see the outline of the navigation bar but I am unable to select it or add any bar buttons to it, it also doesn't appear in the hierarchical view.

view

However if I select the "push (deprecated)" option when choosing the type of segue, I am able to select the navigation bar in VC_B and add buttons to it, it also show up in the hierarchical view as a Navigation Item.

The only work around I can find is to choose show, then change the segue to push(deprecated) in the Attribute Inspector so the Navigation Item will show up in the hierarchical view, then change the segue back to show. But I am worry that this might cause problems further down the line.

Is there a way to add a Bar Button to VC_B's navigation bar without using the work around?

Just drag the "Navigation Item" from object library to the navigation bar and it should work as expected. You can make changes as you like and it works exactly like in Xcode 5.

Your storyboard should look like this

In your appDelegate.m inside your didFinishLaunchingWithOptions

//authenticatedUser: check from NSUserDefaults User credential if its present then set your navigation flow accordingly

if (authenticatedUser) 
{
    self.window.rootViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateInitialViewController];        
}
else
{
    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"LoginViewController"];
    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];

    self.window.rootViewController = navigation;
}

In SignUpViewController.m file

- (IBAction)actionSignup:(id)sender
{
    AppDelegate *appDelegateTemp = [[UIApplication sharedApplication]delegate];

    appDelegateTemp.window.rootViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateInitialViewController];
}

In file MyTabThreeViewController.m

- (IBAction)actionLogout:(id)sender {

    // Delete User credential from NSUserDefaults and other data related to user

    AppDelegate *appDelegateTemp = [[UIApplication sharedApplication]delegate];

    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"LoginViewController"];

    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
    appDelegateTemp.window.rootViewController = navigation;

}

Swift 4 Version

didFinishLaunchingWithOptions in app delegate assuming your initial view controller is the signed in TabbarController.

if Auth.auth().currentUser == nil {
        let rootController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "WelcomeNavigation")
        self.window?.rootViewController = rootController
    }

    return true

In Sign up view controller:

@IBAction func actionSignup(_ sender: Any) {
let appDelegateTemp = UIApplication.shared.delegate as? AppDelegate
appDelegateTemp?.window?.rootViewController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateInitialViewController()
}

MyTabThreeViewController

 //Remove user credentials
guard let appDel = UIApplication.shared.delegate as? AppDelegate else { return }
        let rootController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "WelcomeNavigation")
        appDel.window?.rootViewController = rootController
