Ios 在不重新启动应用程序的情况下，语言更改无法正常工作

更改语言后，键盘仍显示以前的语言

同样适用于相机和其他物品

这是我登录页面的代码

 let actionSheetController = UIAlertController(title: "Select App Language", message: nil, preferredStyle: .actionSheet)
      actionSheetController.addAction(UIAlertAction(title: "Arabic", style: .default, handler: { (alert) in
        if currentLanguage != "ar"
        {
      // DispatchQueue.main.async {
      UIView.appearance().semanticContentAttribute = .forceRightToLeft
      UINavigationBar.appearance().semanticContentAttribute = .forceRightToLeft
      let storyboard = UIStoryboard(name: "Main", bundle: nil)
      // the view controller that you want to show after changing the language
      let viewController = storyboard.instantiateViewController(withIdentifier: "LoginVC") as! UINavigationController
        LanguageManager.shared.setLanguage(language: .ar, rootViewController: viewController) { (view) in
        self.userDefaults.set(["ar","en"], forKey: "AppleLanguages")
//        self.userDefaults.setValue(["lo","en"], forKey: "AppleLanguages")

        L10n.shared.language = "ar"
        currentLanguage = "ar"
        self.userDefaults.set(currentLanguage, forKey: "currentLanguage")
        self.userDefaults.synchronize()
        view.transform = CGAffineTransform(scaleX: 2, y: 2)
        view.alpha = 0

      }
        }
      // }
    }))
    actionSheetController.addAction(UIAlertAction(title: "English", style: .default, handler: { (alert) in
      // DispatchQueue.main.async {
        if currentLanguage != "en"
        {
      UIView.appearance().semanticContentAttribute = .forceLeftToRight
      UINavigationBar.appearance().semanticContentAttribute = .forceLeftToRight
      let storyboard = UIStoryboard(name: "Main", bundle: nil)
      // the view controller that you want to show after changing the language
      let viewController = storyboard.instantiateViewController(withIdentifier: "LoginVC") as! UINavigationController
      LanguageManager.shared.setLanguage(language: .en, rootViewController: viewController) { (view) in
        self.userDefaults.set(["en","ar"], forKey: "AppleLanguages")
        // self.userDefaults.setValue(["en","lo"], forKey: "AppleLanguages")
        L10n.shared.language = "en"
        currentLanguage = "en"
        Bundle.setLanguage("en")
        self.userDefaults.set(currentLanguage, forKey: "currentLanguage")
        self.userDefaults.synchronize()
        //LanguageManager.shared.defaultLanguage = .en
        view.transform = CGAffineTransform(scaleX: 2, y: 2)
        view.alpha = 0

      }
        }
      // }
    }))
    actionSheetController.addAction(UIAlertAction( title: "z_cancel".getLocalizedValue(), style: .cancel, handler: { (alert) in
      return
    }))
    if UIDevice.current.userInterfaceIdiom == .pad {
      let popoverController = actionSheetController.popoverPresentationController
      popoverController?.sourceView = self.view
      popoverController?.sourceRect = self.view.bounds
    }
    self.present(actionSheetController, animated: true, completion: nil)

在这里输入代码

在AppDelegate中

if let currentLang = userDefaults.value(forKey: "currentLanguage") as ? String {
    if currentLang == "ar" {
        LanguageManager.shared.defaultLanguage = .ar
        LanguageManager.shared.setLanguage(language: .ar)
    }
    else {
        LanguageManager.shared.setLanguage(language: .en)
    }
    currentLanguage = currentLang
    L10n.shared.language = currentLang
}
