在iOS中, 可以使用MessageUI.framework框架发送短信, 步骤如下:

代码下载http://git.oschina.net/yao_yu/swift_likecs_samples/tree/master/Y0001_SendSMS

1. 添加MessageUI.framework框架

2. 为ViewController类

   • 添加UINavigationControllerDelegate, MFMessageComposeViewControllerDelegate 接口
   • 实现func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult)

3. 发送短信很简单

   func sendSMS(){
       if MFMessageComposeViewController.canSendText(){
           let controller = MFMessageComposeViewController()
           controller.body = txtSMS.text
           controller.recipients = txtTo.text.componentsSeparatedByString(",")
           controller.messageComposeDelegate = self
           self.presentViewController(controller, animated: true, completion: nil)
       } else {
           let alert = UIAlertView(title: "提示信息", message: "本设备不能发短信", delegate: nil, cancelButtonTitle: "确定")
           alert.show()
       }
   }
   
   func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
   
       controller.dismissViewControllerAnimated(true, completion: nil)
   
       switch result.value{
       case MessageComposeResultSent.value:
           lblResult.text = "短信已发送"
       case MessageComposeResultCancelled.value:
           lblResult.text = "短信已取消"
       case MessageComposeResultFailed.value:
           lblResult.text = "短信发送失败"
       default:
           break
       }
   }
