Adaptive show detail segue transformed to modal instead of push on iPhone when master view controller is a UITabBarController

Question

In XCode 6, if you create a new project based on the Master-Detail Application template, you get a universal storyboard that is supposed to be good for all devices.

When

Answer 1

The docs state when the split controller is collapsed, it handles showDetail by calling show on the master view controller, which in your case is a tab controller. You need to forward that on to the child nav controller as follows:

1. Make a tab controller subclass.
2. In the storyboard set the tab controller to use the new subclass.
3. Add this method to the subclass:

- (void)showViewController:(UIViewController *)vc sender:(id)sender{
    [self.viewControllers.firstObject showViewController:vc sender:sender];
}

This forwards it on to the nav controller in the first tab.
