iOS-发短信

在APP内如何发短信呢?

MFMessageComposeViewController这个类提供了发短信的功能。

例子

guard MFMessageComposeViewController.canSendText() else {
            print("不能发送短信")
            return
        }
        let messageVC = MFMessageComposeViewController()
        messageVC.messageComposeDelegate = self // 代理
        messageVC.recipients = ["18888888888"] // 收件人
        messageVC.body = "短信内容" // 内容
        // 发送主题
        if MFMessageComposeViewController.canSendSubject() {
            messageVC.subject = "ICE"
        }
        // 发送附件
        if MFMessageComposeViewController.canSendAttachments() {
            // 路径添加
            if let path = Bundle.main.path(forResource: "Info", ofType: "plist") {
                messageVC.addAttachmentURL(URL(fileURLWithPath: path), withAlternateFilename: "Info.plist")
            }
            // NSData添加
            if MFMessageComposeViewController.isSupportedAttachmentUTI("public.png") {
                // See [Uniform Type Identifiers Reference](https://developer.apple.com/library/ios/documentation/Miscellaneous/Reference/UTIRef/Introduction/Introduction.html)
                if let image = UIImage(named: "qq") {
                    if let data = UIImagePNGRepresentation(image) {
                        // 添加文件
                        messageVC.addAttachmentData(data, typeIdentifier: "public.png", filename: "qq.png")
                    }
                }
            }
        }
        // messageVC.disableUserAttachments() // 禁用添加附件按钮
        self.present(messageVC, animated: true, completion: nil)
