How to add UISearchBar in middle to the navigation bar.

I am not sure why you want the UISearchBar on the navigation bar. Normally the implementation is just below the Navigation bar, and you can set it as your tableHeaderView

But for adding the Searchbar to your navigation bar, you cannot add the UISearchBar directly. You can add the Navigation Bar, and your UISearchBar as subviews to a view (lets say comboView) and then add it to your self.view or your tableHeaderView.

UIView * comboView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 45)];
[comboView addSubview:navigationBar];
[comboView addSubview:searchBar];

// You should have allocated the navigation bar and the search bar before this though.

self.tableView.tableHeaderView= comboView;
