一.需要导入messageUI.Frameworks(#import<messageUI/messageUI.h>)

二.步骤:

if NSClassFromString("MFMessageComposeViewController") != nil {    if MFMessageComposeViewController.canSendText() {       let messageCompose = MFMessageComposeViewController()       // 收信人       messageCompose.recipients = ["13807043589", "13807043581"]       // 短信内容       messageCompose.body = "短信内容";       if MFMessageComposeViewController.canSendSubject() {           // 短信主题           messageCompose.subject = "短信主题"       }       // 代理       messageCompose.messageComposeDelegate = self       self.present(messageCompose, animated: true, completion: nil)     } else {          // 不能发送短信          let str = "sms://13807043589&body=短信内容&subject=短信主题".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)          let url = URL(string: str)!          if UIApplication.shared.canOpenURL(url) {              UIApplication.shared.openURL(url)          }     }} else {     // 系统版本低于iOS 4.0     let str = "sms://13807043589&body=短信内容&subject=短信主题".addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)     let url = URL(string: str)!     if UIApplication.shared.canOpenURL(url) {         UIApplication.shared.openURL(url)     }}

代理(必须实现):

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