I'm trying (for experiment) to work with multiple storyboards. The first storyboard (starts at startup) contains only one view controller that executes some code and download json data from a website.

first storyboard

When finish the download task, the view controller (of first storyboard) set the entry Point of Second storyboard as root view controller after instantiating it.

UIStoryboard *mainSB = [UIStoryboard storyboardWithName:@"SecondStoryboard" bundle:[NSBundle mainBundle]];
    UITabBarController *rootTabBarController = (UITabBarController *)[mainSB instantiateInitialViewController];

    dispatch_sync(dispatch_get_main_queue(), ^{

        ...

        self.view.window.rootViewController = rootTabBarController;

This Second story board contains a tabbar controller with a split view controller inside it:

second storyboard

All works but there is a strange behaviour of navbar controller inside the splitview controller. Its back button works if pressed but doesn't display properly because there is only the "back" text without the left arrow.

![the problem with navigation bar]3

Only after few minutes and some transitions between master and detail view the back button display properly with the left arrow.

navigation bar ok after some transitions

(All works correctly if I use only the Second storyboard from the startup)

I Know that in this case I can use only one storyboard but I want to know if is not correct to work in this way with multiple storyboards or if it's a bug.

  • Do you know that it works if you have all the controllers in one storyboard? BTW, Apple says that a split view controller should only be the root view controller of the window, not embedded in a tab bar controller. – rdelmar Jun 07 '15 at 06:21
  • @rdelmar Yes, if I have all the controller in the same storyboard and perform the specific segue it all works. [StoryBoard](http://i57.tinypic.com/2psk1vp.png) However, with the TabBar controller and a UISplitView inside it I haven't any problems. – Damiano Di Stefano Jun 07 '15 at 10:13
  • I tried to remove the UISplitViewController from the second storyboard and leave only the UINavigationController. Everything works, so the problem is the UISplitViewController. – Damiano Di Stefano Jun 07 '15 at 10:53

With the new Xcode 7 Beta and iOS 9 all perfectly work.

Whit the same configuration of files the chevron of navigation controller display properly. I don't know why, Apple in this WWDC has released the storyboard reference, but I think that was a bug of UISplitViewController.
