swift - 使用 MFMessageComposeViewController 在 swift 中打开带有文本和 url 的短信应用程序

Question

嗨，我想打开带有奶嘴的短信应用程序，我写了以下代码，但我面临

错误如下:静态成员“canSendText”不能在“MFMessageComposeViewController”类型的实例上使用

var controller1 = MFMessageComposeViewController()
    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

            if indexPath.section == 0
            {
                if (controller1.canSendText()) {

                    let urlToShare = "http://www.appzoy.com"

                    controller1.body = "Hey I just gave an Awesome Assessment on UAssess App you can also try it. I scored , Try to beat my score \(urlToShare)"

                    controller1.messageComposeDelegate = self as? MFMessageComposeViewControllerDelegate
                    self.present(controller1, animated: true, completion: nil)
                }
            }
    }

如 doc 中所述你应该使用:

if MFMessageComposeViewController.canSendText() {
    print("SMS services are available")
}
