공유하기

    private func openURL(url: URL?) {
        guard let url = url else { return }
        if UIApplication.shared.canOpenURL(url) {
            if #available(iOS 10.0, *) {
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
                } else {
                UIApplication.shared.openURL(url)
            }
        }
    }

    private func shareSNS(sns: SNS) {
        let shareURL = "https://hogehogehogeho.com"
        switch sns {
        case .facebook:
            guard let composeViewController: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook) else { return }
            composeViewController.setInitialText(shareURL)
            self.present(composeViewController, animated: true, completion: nil)
        case .line:
            guard let scheme: String = "line://msg/text/\(shareURL)".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) else { return }
            self.openURL(url: URL(string: scheme))
        case .mail:
            guard let string = "mailto:[email protected]?body=\(shareURL)".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) else { return }
            self.openURL(url: URL(string: string))
        case .twitter:
            guard let vc = SLComposeViewController(forServiceType:SLServiceTypeTwitter) else { return }
            vc.setInitialText(shareURL)
