I have an UITabBar controller managing several controllers (using SDK 3.0). One of these is a tableView controller and I need to provide a search capability using the UISearchDisplayController. All of my code is based on Apple TableSearch example. However, when clicking on the tab, the tableView controller appears showing its related content, but no searchBar appears. I have checked the xib in IB to make sure that all of the outlets are properly set, but no matter what I try self.searchDisplayController is always nil and the search bar does not appear.

In practice I have replicated MainView.xib from the TableSearch example and set the file’s owner class to the correct controller class for the tab. The outlets are sets as in the example MainView.xib. Am i missing any important step or doing something wrong?

Thank you in advance.

    Ok, I have found how to solve it. In my case, the problem was due to the fact that I was using a controller embedded within the UITabBarController as one of its managed tabs (i.e. as a child).

    Removing the controller from the UITabBarController, then adding an UINavigationController to the UITabBarController instead, and finally putting my controller as a child of the UINavigationController solved completely the issue.

    I do not understand why this is so (there is no related information in the documentation, as often happens); however, it now works like a charm.
    With kind regards.
