打电话、发短信、发邮件算是比较APP小的功能，今天来总结下。

一、添加框架<MessageUI/MessageUI.h>

@implementation ViewController
 
- (void)viewDidLoad {
    [super viewDidLoad];
    //发送短信
    UIButton *btnSendMessage=[UIButton buttonWithType:UIButtonTypeSystem];
    [btnSendMessage setTitle:@"发送短信" forState:UIControlStateNormal];
     btnSendMessage.frame=CGRectMake(100, 100, 80, 50);
    [btnSendMessage addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    btnSendMessage.tag=10001;
    [self.view addSubview:btnSendMessage];
     
    //发送邮件
    UIButton *btnSendMail=[UIButton buttonWithType:UIButtonTypeSystem];
    [btnSendMail setTitle:@"发送邮件" forState:UIControlStateNormal];
    btnSendMail.frame=CGRectMake(200, 100, 80, 50);
    [btnSendMail addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    btnSendMail.tag=10002;
    [self.view addSubview:btnSendMail];
     
    //打电话
    UIButton *btnTel=[UIButton buttonWithType:UIButtonTypeSystem];
    [btnTel setTitle:@"打电话" forState:UIControlStateNormal];
    btnTel.frame=CGRectMake(300, 100, 80, 50);
    [btnTel addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
    btnTel.tag=10003;
    [self.view addSubview:btnTel];
     
}
-(void)btnClick:(UIButton *)sender
{
    UIButton *btn=(UIButton *)sender;
    if (btn.tag==10001) {//短信
//        1.不能指定短信内容，而且不能自动回到原应用
//        NSURL *url = [NSURL URLWithString:@"sms://18575533040"];
//        [[UIApplication sharedApplication] openURL:url];
//        2.使用MessageUI框架
        if (![MFMessageComposeViewController canSendText]) {
            UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"不支持短信发送" message:@"该设备不支持发送短信功能" delegate:self cancelButtonTitle:@"YES" otherButtonTitles:nil, nil];
            [alertView show];
            return;
        }
        MFMessageComposeViewController *messageVc=[[MFMessageComposeViewController alloc]init];
        messageVc.messageComposeDelegate=self;
        //接收人
        messageVc.recipients=@[@"18575533040",@"10010"];
        //短信内容
        messageVc.body=@"body";
        //短信主题
        messageVc.subject=@"subject";
        //模态视图
        [self presentViewController:messageVc animated:YES completion:nil];
    }
    else if (btn.tag==10002)  //邮件
    {
        MFMailComposeViewController *mailVc=[[MFMailComposeViewController alloc]init];
        [mailVc setSubject:@"主题"];
        //收件人
        [mailVc setToRecipients:@[@"991843897@qq.com"]];
        //抄送
        [mailVc setCcRecipients:@[@"991843897@qq.com"]];
        //密送
        [mailVc setBccRecipients:@[@"991843897@qq.com"]];
        //正文
        [mailVc setMessageBody:@"这是我的<font color=\"blue\">工作报告</font>，请审阅！" isHTML:YES];
        //附件
        UIImage *img=[UIImage imageNamed:@"email.png"];
        NSData *data=UIImagePNGRepresentation(img);
        //Data二进制数据  mimeType 使用什么应用程序打开附件  fileName收件人接受时看到的附件名  可以添加多个附件
        [mailVc addAttachmentData:data mimeType:@"image/png" fileName:@"图标.png"];
        //设置代理
        [mailVc setMailComposeDelegate:self];
        //显示控制器
        [self presentViewController:mailVc animated:YES completion:nil];
         
    }
    else if (btn.tag==10003) //电话
    {
//        打电话有3种方式:
////        1.不回应用  直接拨号,拨号完成后停留在通话记录中
//        NSURL *telurl=[NSURL URLWithString:@"tel://18575533040"];
//        [[UIApplication sharedApplication]openURL:telurl];
         
         
////        2.出去打电话然后回来
//        telprompt协议属于苹果的私有协议，一旦程序中使用了此协议，程序无法上架  针对越狱的机器开发的系统，可以使用此协议
//        NSURL *telPromptUrl=[NSURL URLWithString:@"telprompt://18575533040"];
//        [[UIApplication sharedApplication]openURL:telPromptUrl];
         
         
//        3.借助WebView打电话
        UIWebView *webView=[[UIWebView alloc]init];
        webView.frame=self.view.bounds;
        [self.view addSubview:webView];
        if (webView) {
            NSURL *url=[NSURL URLWithString:@"tel://18575533040"];
            NSURLRequest *request=[NSURLRequest requestWithURL:url];
             
            [webView loadRequest:request];
        }
         
    }
}
//短信代理
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
//    enum MessageComposeResult {
//        MessageComposeResultCancelled, 取消
//        MessageComposeResultSent,      发送
//        MessageComposeResultFailed     失败
//    };
//    typedef enum MessageComposeResult MessageComposeResult;
    NSLog(@"%d",result);
    //移除
    [self dismissViewControllerAnimated:YES completion:nil];
}
//邮件代理
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
//    enum MFMailComposeResult {
//        MFMailComposeResultCancelled, 取消
//        MFMailComposeResultSaved,     保存
//        MFMailComposeResultSent,      发送
//        MFMailComposeResultFailed     失败
//    };
//    typedef enum MFMailComposeResult MFMailComposeResult;
    NSLog(@"%d",result);
    if (result==2) {
        UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"发送邮件通知" message:@"发送邮件成功" delegate:self cancelButtonTitle:@"YES" otherButtonTitles:nil, nil];
        [alertView show];
    }
    [self dismissViewControllerAnimated:YES completion:nil];
