系统服务之打电话、发短信、发邮件

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>

二、

@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:@[@"[email protected]"]];

        //抄送

        [mailVc setCcRecipients:@[@"[email protected]"]];

        //密送

        [mailVc setBccRecipients:@[@"[email protected]"]];

        //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];

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.
