此方法将打开“设置”〉“您的应用”。它将显示所有可用的隐私切换，如相机、照片、通知、Hive数据等。
在下面@Mischa的评论之后，测试并更新了对此的回答（更简洁）：

if let appSettings = URL(string: UIApplication.openSettingsURLString), UIApplication.shared.canOpenURL(appSettings) {
    UIApplication.shared.open(appSettings)
}

上一个答案：

我发现这个问题的答案（虽然很有帮助）有太多的假设逻辑。如果有人碰到这个问题，这里有一个简单明了的Swift 5实现：

if let bundleIdentifier = Bundle.main.bundleIdentifier, let appSettings = URL(string: UIApplication.openSettingsURLString + bundleIdentifier) {
    if UIApplication.shared.canOpenURL(appSettings) {
        UIApplication.shared.open(appSettings)
    }
}

对于Swift 3，使用UIApplicationOpenSettingsURLString转到应用程序的设置，其中显示通知状态和“Hive数据”

let settingsButton = NSLocalizedString("Settings", comment: "")
let cancelButton = NSLocalizedString("Cancel", comment: "")
let message = NSLocalizedString("Your need to give a permission from notification settings.", comment: "")
let goToSettingsAlert = UIAlertController(title: "", message: message, preferredStyle: UIAlertControllerStyle.alert)

goToSettingsAlert.addAction(UIAlertAction(title: settingsButton, style: .destructive, handler: { (action: UIAlertAction) in
    DispatchQueue.main.async {
        guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
            return
        }

        if UIApplication.shared.canOpenURL(settingsUrl) {
            if #available(iOS 10.0, *) {
                UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                    print("Settings opened: \(success)") // Prints true
                })
            } else {
                UIApplication.shared.openURL(settingsUrl as URL)
            } 
        }
    }
}))

logoutUserAlert.addAction(UIAlertAction(title: cancelButton, style: .cancel, handler: nil))

雨燕五：

if let url = URL(string: UIApplication.openSettingsURLString) {
    UIApplication.shared.open(url)
}

**更新：**这将被Apple拒绝。

要打开设置的通知部分，请使用此

UIApplication.shared.open(URL(string:"App-Prefs:root=NOTIFICATIONS_ID")!, options: [:], completionHandler: nil)

从iOS 15.4开始，我们可以直接使用UIApplicationOpenNotificationSettingsURLString深入链接到通知设置屏幕：
https://developer.apple.com/documentation/uikit/uiapplicationopennotificationsettingsurlstring?language=objc

这应该可以让你覆盖所有的iOS版本，包括iOS 15和iOS 16。

extension UIApplication {
  private static let notificationSettingsURLString: String? = {
    if #available(iOS 16, *) {
      return UIApplication.openNotificationSettingsURLString
    }

    if #available(iOS 15.4, *) {
      return UIApplicationOpenNotificationSettingsURLString
    }

    if #available(iOS 8.0, *) {
      // just opens settings
      return UIApplication.openSettingsURLString
    }

    // lol bruh
    return nil
  }()

  private static let appNotificationSettingsURL = URL(
    string: notificationSettingsURLString ?? ""
  )

  func openAppNotificationSettings() -> Bool {
    guard
      let url = UIApplication.appNotificationSettingsURL,
      self.canOpen(url) else { return false }
    return self.open(url)
  }
}

用法：

Button {
  let opened = UIApplication.shared.openAppNotificationSettings()
  if !opened {
    print("lol fail")
  }
} label: {
  Text("Notifications")
}
