Question

在本地化图像时，我使用以下代码：

 UIImage* localTutorial = [UIImage imageNamed:NSLocalizedString(@"tutorial.png", nil)];

我想本地化UIBarButtonItem并根据本地化字符串更改它的标题，我该如何实现。提前谢谢。

Answer 1

你做错了，按以下方式使用的方法

 NSString *barButtonItemTitle = NSLocalizedString(@"Button title here", @"")
 UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:barButtonItemTitle
            style:UIBarButtonItemStyleBordered target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;

Answer 2

您可以使用

- (id)initWithImage:(UIImage *)image style:(UIBarButtonItemStyle)style target:(id)target action:(SEL)action

或

- (id)initWithTitle:(NSString *)title style:(UIBarButtonItemStyle)style target:(id)target action:(SEL)action

Answer 3

快捷键：

// MARK: - Lifecycle Methods
override func viewDidLoad() {

    super.viewDidLoad()

    // if it's the back button
    self.navigationItem.backBarButtonItem = UIBarButtonItem(title: NSLocalizedString("action_close", comment: ""), style: .plain, target: self, action: #selector(self.didTapMyLocalizedBarButtonItem))

    // OR maybe you need the following instead (like I did):

    // if this is the root view controller for the current navigation controller (therefore, it's not a back button technically)
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: NSLocalizedString("action_close", comment: ""), style: .plain, target: self, action: #selector(self.didTapMyLocalizedBarButtonItem))
}

// MARK: - Custom Button Action
@IBAction func didTapMyLocalizedBarButtonItem(_ sender: Any) {
    print("Custom bar button item tapped.")
}
