Answer 1

使用此

    if MFMessageComposeViewController.canSendText() == true{
        let recipients:[String] = ["1500"]
        var messageController = MFMessageComposeViewController()
        //messageController.messageComposeDelegate = self // implement delegate if you want
        messageController.recipients = recipients
        messageController.body = "Your_text"
        self.present(messageController, animated: true, completion: nil)

    }

您需要将“MessageUI”导入您的班级并使用以下代码。

func sendMessages() {   
    if MFMessageComposeViewController.canSendText() == true {
        let recipients:[String] = ["9895249619"]
        let messageController = MFMessageComposeViewController()
        messageController.messageComposeDelegate  = self
        messageController.recipients = recipients
        messageController.body = "Your_message_text"
        self.present(messageController, animated: true, completion: nil)
    } else {
        //handle text messaging not available
    }
}

func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {    
    controller.dismiss(animated: true, completion: nil)
}
