Proper segue flow

I am looking for the best-practice method of doing the following:

I have two TabBarController views embedded in a NavigationController and one which I don't want to include as a tab but is embedded in a NavigationController:

  1. FeedView (TableViewController)

  2. VenueView (CollectionViewController)

  3. SelectView (ViewController)

In VenueView (2), I have the following code to bring up SelectView (3):

override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {

let selectVC: SelectViewController! = self.storyboard?.instantiateViewControllerWithIdentifier("selectVC") as! SelectViewController

selectVC.currentVenue = venueItems[indexPath.row]    
    presentViewController(selectVC, animated: true, completion: nil)

}

This segue works, however SelectView(3) doesn't have a navigation bar at the top although it is embedded in a separate NavigationController. If I hook it up to the other NavController in the IB, it adopts/becomes the third tab in the BarTabController. I don't want that.

How do I hook it up so that there is a NavBar (with a back button that will go back to either view) but no Tab?

Also, there is a button on SelectView(3). When this button is tapped I'd like it to segue to FeedView(1) - while persisting some data ie 'pushing into the feed'. What kind of segue should I use for this? I've tried many combinations and ran into some strange bugs and I find View management very confusing.

Storyboard image below for reference Views are in order from top to bottom (1-3):

Solution

  • In order to do this you need to fix your problem, you need to present the navigation controller which contains SelectView but not SelectView itself as you do now.

    You should set a storyboard identifier to your 3'rd navigation controller and apply this change:

    let selectNavigationController = self.storyboard?.instantiateViewControllerWithIdentifier("selectNavigationController") as! UINavigationController
let selectVC = selectNavigationController.topViewController as! SelectViewController
selectVC.currentVenue = venueItems[indexPath.row]

presentViewController(selectNavigationController, animated: true, completion: nil)
