I have been searching high and low for an answer to this but none are for storyboards.
I have used this tutorial for creating my splitview and it works however the following part:
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
splitViewController.delegate = (id)navigationController.topViewController;
Won't work of course because the splitview is in a tabview.
How do I set my DetailViewController as the delegate?
The problem was because I was setting the SplitViewController as the root view in the delegate.
I changed it to:
UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
UISplitViewController *splitViewController = [tabBarController.viewControllers lastObject];//(UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
splitViewController.delegate = (id)navigationController.topViewController;
And it works perfectly.
It has also been approved by Apple.
