UISearchController breaks the UI when the search bar becomes active when in a grouped style UITableView

Originator:ben
Number:rdar://21749311 Date Originated:09-July-2015
Status:Closed Resolved:
Product:iOS Product Version:8.0
Classification: Reproducible:
 
Summary:
When using a UITableView with the group style and a large section header, when the UISearchController becomes active (user taps the search bar) it will break the UINavigationController's UINavigationBar and not show the standard searching UI with the cancel button. Also the automatic content insets are off when the UISearchController's search bar is set as the UITableView's tableHeaderView.

Steps to Reproduce:
1. Launch the app
2. Tap the search bar text field to begin search, the UI will now be in a broken state.

Expected Results:
The search bar should look like it does when used with a Plain UITableView style with the search bar in the UINavigationBar and the cancel button in the right bar button items area.

Actual Results:
The UINavigationBar breaks by disappearing and none of the search UI is visible (though the keyboard does come up). This leaves the view in an unusable state that can only be fixed by reloading the view hierarchy completely (restarting the app or popping the view controller and causing a full reload).

Version:
iOS 8.4, 8.3

So I checked my example using iOS 9 and Xcode 7 b4 and everything works as expected. But when using Xcode 7 b4 and running the iOS Simulator for iOS 8.4/8.3 it is still present (I'm assuming it's due to the bug being in the bundled iOS 8.x frameworks).
