如何从ios应用发送禁止编辑的消息正文和收件人号码

import MessageUI

class ViewController: UIViewController, MFMessageComposeViewControllerDelegate {
    
    func sendSMS() {
        if MFMessageComposeViewController.canSendText() {
            let messageVC = MFMessageComposeViewController()
            messageVC.body = "这是禁止编辑的消息正文"
            messageVC.recipients = ["收件人号码"]
            messageVC.messageComposeDelegate = self
            present(messageVC, animated: true, completion: nil)
        } else {
            // 设备不支持发送短信功能
            // 处理错误情况
        }
    }
    
    // MFMessageComposeViewControllerDelegate方法，用于处理发送结果
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
        dismiss(animated: true, completion: nil)
        
        // 根据发送结果进行相应处理
        switch result {
        case .cancelled:
            // 用户取消发送
            break
        case .sent:
            // 短信发送成功
            break
        case .failed:
            // 短信发送失败
            break
        @unknown default:
            break
        }
    }
}
