iOS7: How to add a fixed Search Bar like Contacts

问题:

After I search a lot of questions and answers, no good result. So I have to ask it here:

I want to add a Search Bar below the navigation bar.

This search bar should be fixed. Just like contacts on iOS7 below.

Can any one help me to figure it out?

You have a view controller. It has a main view. Inside that main view is a search bar (UISearchBar) and, below that, a table view (UITableView).

Your view controller is embedded in a navigation controller (UINavigationController).

UINavigationController

MyViewController (UINavigationController) - child of the navigation controller

UIView - main view of MyViewController

|--- UISearchBar (subview of UIView)
|
|--- UITableView (another subview of UIView)
