I use
self.searchDisplayController.displaysSearchBarInNavigationBar = YES;
to display the searchBar in the navigationBar. This used to work great, except that in iOS 8.3 the searchBar does not appear anymore.
I still use the UISearchDisplayController as I want my app to support iOS 7. My understanding is that even though a class is deprecated, it should still work in subsequent OS versions.
Has anyone noticed this as well and perhaps solved it?
