Issue with UITabBarViewController as master of UISplitViewController in iOS 8.3

Question

For a project that I'm working on, I've put together an UITabBarViewController as master of UISplitViewController in a universal app running in iPad simulator, it used to work fine in iOS 7.1 and iOS 8.2 but with iOS 8.3 it crashes with the message:

Could not load NIB in bundle: 'NSBundle (loaded)' with name 'Z6l-Hd-h3H-view-7sH-l5-cWr''

Please notice that if you change the simulator to one of version 7.1 or 8.2 it works ok, I don't know what I'm doing wrong or what could be causing this behavior.

Here's an example: https://github.com/AresDev/splitwithtabbar

Thanks for your help.

Answer 1

1. Set the item viewcontroller of UITabBarController as UINavigationController rather than UIViewController

2. You can set MasterController of UISplitviewController as directly to the UITabBarController.

3. Its better to set DetailController of UISplitviewController as a UINavigationController.
