iOS:后退按钮标签被自定义字体截断

Question

我正在为导航项使用自定义字体；当我转向另一个 View Controller 时，新呈现的 View Controller 上的后退按钮在左侧被切断。在执行 segue 之前，我在第一个 View Controller 上尝试了 setTitlePositionAdjustment(_ adjustment: UIOffset, for barMetrics: UIBarMetrics) 但它没有取代按钮:

还有

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "Show Contents" {
        if let viewController = segue.destination as? ContentsTableViewController {
                viewController.navigationItem.backBarButtonItem?.setTitlePositionAdjustment(UIOffsetMake(10, 0), for: .default)

        }
    }
}

Answer 1

使用此代码:

override func viewDidLoad() {
    super.viewDidLoad()
    let backBarButtonItem = UIBarButtonItem(title: "خانه", style: .plain, target: nil, action: nil)
    backBarButtonItem.setTitleTextAttributes([.font : UIFont(name: "B Koodak", size: 32)!], for: .normal)
    navigationItem.backBarButtonItem = backBarButtonItem
}

我得到以下信息:
