iPhone:如何以编程方式响应SMS消息

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    if url.scheme == "your-custom-url-scheme" {
        // 解析URL并执行相应的操作
        return true
    }
    return false
}

import MessageUI

func sendSMS() {
    if MFMessageComposeViewController.canSendText() {
        let messageComposeVC = MFMessageComposeViewController()
        messageComposeVC.body = "这是一条SMS消息"
        messageComposeVC.recipients = ["1234567890"]
        messageComposeVC.messageComposeDelegate = self
        present(messageComposeVC, animated: true, completion: nil)
    }
}

func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
    switch result {
    case .sent:
        print("SMS已发送")
    case .failed:
        print("SMS发送失败")
    case .cancelled:
        print("SMS发送已取消")
    @unknown default:
        print("SMS发送结果未知")
    }
    controller.dismiss(animated: true, completion: nil)
}
