ios - 在Swift中向多个收件人发送短信

Question

我想使用 MFMessageComposeViewController 向多个收件人发送一条消息，但无法添加第二个收件人，依此类推

这是我的代码:

@IBAction func sendSms(sender: AnyObject) {

        if (MFMessageComposeViewController.canSendText())
        {
            let controller = MFMessageComposeViewController()
            controller.body = self.textView.text
            controller.recipients = [self.phoneField.text!]
            controller.messageComposeDelegate = self
            self.presentViewController(controller, animated: true, completion: nil)
        }
        else
        {
            print("Error")
        }
    }

extension MyViewController : MFMessageComposeViewControllerDelegate 
{
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult)     
    {
            controller.dismissViewControllerAnimated(true, completion: nil)}
    }
}

有任何建议如何将其发送给多个收件人？

Answer 1

如果用户在文本字段中输入多个电话号码，则需要提示用户使用逗号(或任何其他符号)分隔电话号码，您可以通过该逗号分隔字符串并将其添加到数组中，然后将该数组传递给controller.recipients
这是一个例子

if (MFMessageComposeViewController.canSendText())
        {
            let controller = MFMessageComposeViewController()
            controller.body = self.textView.text
            let phoneNumberString = "123456789,987654321,2233445566"
            let recipientsArray = phoneNumberString.components(separatedBy: ",")
            controller.recipients = recipientsArray
            controller.messageComposeDelegate = self
            self.presentViewController(controller, animated: true, completion: nil)
        }
        else
        {
            print("Error")
        }
