在iOS发送短信

Question

我是iOS正在发展中的全新产品和xCode。 以前我开发的android和我知道我应该与意图合作拨打电话并发送短信在android应用程序。 现在我想开发一个简单的应用程序，当我按Button它发送一个SMS到一个特定的数字。 所以我在我的Ubuntu上安装了Mac OS 10.11​​。 并可以连接我的iPhone 5，并运行我的简单Hello World应用程序在实际iPhone设备而不是simulator。 现在，我创建了一个StoryBoard和Button通过这篇文章让之后一个函数，： Send SMS Message Toturial

也期待在其他环节，是相似的。 这是我的简单ViewController.swift。

import UIKit  
    import MessageUI 

    class ViewController: UIViewController, MFMessageComposeViewControllerDelegate { 

     @IBAction func sendMessage(sender: AnyObject) { 

      print("Send button pressed") //display a text to make sure is calling 

      if (MFMessageComposeViewController.canSendText()) { 
       let controller = MFMessageComposeViewController() 
       controller.body = "TestMessage " 
       controller.recipients = ["xxxxxxxxx", "xxxxxxxxx"] // sending for two numbers 
       controller.messageComposeDelegate = self  
       self.presentViewController(controller, animated: true, completion: nil)  
      }  
     } 
     func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {  
      switch (result.rawValue) {  
      case MessageComposeResultCancelled.rawValue:  
       print("Message was cancelled")  
       self.dismissViewControllerAnimated(true, completion: nil)  
      case MessageComposeResultFailed.rawValue:  
       print("Message failed")  
       self.dismissViewControllerAnimated(true, completion: nil)  
      case MessageComposeResultSent.rawValue:  
       print("Message was sent")  
       self.dismissViewControllerAnimated(true, completion: nil) 
      default: 
       break; 
} 
     } 

     override func viewDidLoad() { 
      super.viewDidLoad() 

      // Do any additional setup after loading the view, typically from a nib. 

     } 



     override func didReceiveMemoryWarning() { 

      super.didReceiveMemoryWarning() 

      // Dispose of any resources that can be recreated. 

    } 

} 

又创造了Simple按钮和链接，上面sendMessage。 当我运行应用程序，显示按钮，当我按下它，它似乎是做某事，但短信不发送。 任何想法？ 我真的很感激它。

更新：正如我们的朋友说我添加print("Send button pressed")在sendMessage Button，所以我找到按钮调用sendMessage当我按下它。

我终于做到了，我用了两种解决方案， 首先，我改变了功能的sendMessage并重新命名为sendText，以这样的方式

@IBAction func sendText(sender: AnyObject) { 
    if (MFMessageComposeViewController.canSendText()) { 
     let controller = MFMessageComposeViewController() 
     controller.body = "Text Body" 
     controller.recipients = ["xxxxxxxxxxx"] 
     controller.messageComposeDelegate = self 
     self.presentViewController(controller, animated: true, completion: nil) 
    } 
} 

和MessageComposeViewController的协议是：

func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) { 
    switch (result.rawValue) { 
    case MessageComposeResultCancelled.rawValue: 
     print("Message was cancelled") 
     self.dismissViewControllerAnimated(true, completion: nil) 
    case MessageComposeResultFailed.rawValue: 
     print("Message failed") 
     self.dismissViewControllerAnimated(true, completion: nil) 
    case MessageComposeResultSent.rawValue: 
     print("Message was sent") 
     self.dismissViewControllerAnimated(true, completion: nil) 
    default: 
     break; 
    } 
} 

，然后点击在故事板的按钮，然后按control键并拖动按钮的ViewController并选择sendText功能，现在它工作正常。

Thx给我的朋友@Kabiroberai寻求帮助并给予一些时间。

继承人的底层函数转换为SWIFT 4：

func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) { 
    switch (result.rawValue) { 
    case MessageComposeResult.cancelled.rawValue: 
     print("Message was cancelled") 
     self.dismiss(animated: true, completion: nil) 
    case MessageComposeResult.failed.rawValue: 
     print("Message failed") 
     self.dismiss(animated: true, completion: nil) 
    case MessageComposeResult.sent.rawValue: 
     print("Message was sent") 
     self.dismiss(animated: true, completion: nil) 
    default: 
     break; 
    } 
}
