在 Facebook 上分享 IOS 11 Swift

Question

Share Button to facebook 11以下的版本可以正常使用，但是11版本这个功能不可用。你有什么建议？

if SLComposeViewController.isAvailable(forServiceType: SLServiceTypeFacebook) {
        var vc: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
        vc.setInitialText("My text")
        self.present(vc, animated: true, completion: nil)
    }

Answer 1

所有社交常量（facebook、twitter、LinkedIn 等）已在 iOS 11 上弃用。
