Navigation bar gets hidden on tapping UISearchbar's cancel button

Question

Issue with navigation bar. Scenario is as -

After successful search, I tapped on a result/cell in table view and move to next screen for details of search result, coming back on search results screen tapped on cancel button. It resets the UISearchBar but it hides the navigation bar.

1. Before Search

2. On tapping search bar

3. After coming back from details screen to search results screen (Navigation bar gets hidden)

I have tried

self.navigationController.navigationBar.hidden = NO;

in

searchBarCancelButtonClicked:(UISearchBar *)searchBar

but no luck.
