class SearchBarContainerView: UIView {  
  let searchBar: UISearchBar  
  init(customSearchBar: UISearchBar) {  
    searchBar = customSearchBar  
    super.init(frame: CGRect.zero)  

    addSubview(searchBar)  
  }

  override convenience init(frame: CGRect) {  
    self.init(customSearchBar: UISearchBar())  
    self.frame = frame  
  }  

  required init?(coder aDecoder: NSCoder) {  
    fatalError("init(coder:) has not been implemented")  
  }  

  override func layoutSubviews() {  
    super.layoutSubviews()  
    searchBar.frame = bounds  
  }  
}  

class MyViewController: UIViewController {  
  func setupNavigationBar() {  
    let searchBar = UISearchBar()  
    let searchBarContainer = SearchBarContainerView(customSearchBar: searchBar)  
    searchBarContainer.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 44)  
    navigationItem.titleView = searchBarContainer  
  }  
}
