更改UISearchBar的宽度

Question

我有一个汉堡包菜单，我正在使用tableView显示一个viewController。问题是我已经在titleView中添加了一个UISearchBar，你可以看到一些searchBar正在隐藏。有没有办法可以让navigationBar更小或者搜索栏更适合？

    searchBar = UISearchBar(frame: CGRectMake(0, 0, self.revealViewController().rearViewRevealWidth-30, 44))
    searchBar?.delegate = self
    searchBar?.showsCancelButton = false

    var textField = searchBar?.valueForKey("searchField") as UITextField
    textField.backgroundColor = UIColor(rgba: "#414e5c")
    textField.leftViewMode = UITextFieldViewMode.Never
    textField.layer.cornerRadius = 5
    textField.clipsToBounds = true


    searchBar?.placeholder = "Søg efter produkter"
    searchBar?.setPositionAdjustment(UIOffsetMake(0, 0), forSearchBarIcon: UISearchBarIcon.Search)



    textField.borderStyle = UITextBorderStyle.None
    searchController = UISearchDisplayController()
    searchController?.delegate = self
    searchController?.searchResultsDelegate = self
    var buttonSearchBar:UIBarButtonItem = UIBarButtonItem(customView: searchBar!)
    self.navigationItem.leftBarButtonItem = buttonSearchBar
