   今天来讲一下如何让我们的APP可以访问系统的短信和电话功能。首先来说短信功能，比较简单，跟之前的做法差别不大，要使用UIApplication，它是一个单例。我们的功能是点击一个按钮，然后拨通一个内置的电话，需要在button的action中加入如下语句：

   @IBAction func phoneBtn(sender:UIButton){
       // var url1 = NSURL(string: "tel://"+canguanArray[0].tel)
        var url1 = NSURL(string: "tel://10086")
        UIApplication.sharedApplication().openURL(url1!)
    }

        var url1 = NSURL(string: "sms://10086")

 var url1 = NSURL(string: "http://blog.csdn.net/cg1991130")

首先在vc中导入头文件：

import MessageUI

class CaipinDetailViewController: UIViewController,MFMessageComposeViewControllerDelegate 

func canSendText() -> Bool{
    return MFMessageComposeViewController.canSendText()
    }//用来指示一条消息能否从用户处发送
    func configuredMessageComposeViewController() -> MFMessageComposeViewController{
    let messageComposeVC = MFMessageComposeViewController()
        messageComposeVC.messageComposeDelegate = self
        messageComposeVC.body = "HI! \(caipinArray[0].rest) 的 \(caipinArray[0].name) 味道很不错，邀你共享 -来自SoFun的邀请"
        return messageComposeVC
        
    }
     func messageComposeViewController(controller: MFMessageComposeViewController!, didFinishWithResult result: MessageComposeResult) {
        controller.dismissViewControllerAnimated(true, completion: nil)
    }

   @IBAction func share(sender: UIButton) {
        let shareView = ShareViewController()
        self.presentViewController(shareView, animated: true, completion: nil)
    }
    @IBAction func message(sender: UIButton) {
        if self.canSendText(){
        let messageVC = self.configuredMessageComposeViewController()
          presentViewController(messageVC, animated: true, completion: nil)
        } else {
        let errorAlert = UIAlertView(title: "不能发送", message: "你的设备没有短信功能", delegate: self, cancelButtonTitle: "取消")
        }

        
    }
