iOS开发之打电话，发短信，发送邮件

iOS开发中，拨打电话的实现主要有三种方式：

• 直接拨号：拨打完电话之后回不到原来的应用，会停留在通讯录里面，而且是直接拨打，不弹出提示

 - (void)makePhoneCall {
   NSMutableString *string = [[NSMutableString alloc] initWithFormat:@"tel:%@",@“10086"];
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:string]];
}

• 跳出应用打完电话之后回到应用

//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。
 - (void)makePhoneCall {
   NSMutableString *string = [[NSMutableString alloc] initWithFormat:@“telprompt://%@",@“10086"];
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:string]];
}

• 借助UIWebView打电话

- (void)makePhoneCall {
   NSMutableString *string = [[NSMutableString alloc] initWithFormat:@"tel:%@",@“10086"];
   UIWebView *callWebview = [[UIWebView alloc] init];
   [callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:string]]];
   [self.view addSubview:callWebview];
}

iOS调用系统的发短信功能主要有两种：

• 程序外调用系统发短信（不能指定短信内容，且不能自动回到原应用）

NSURL *url = [NSURL URLWithString:@"sms://10010"];
[[UIApplication sharedApplication] openURL:url];

• 程序内调用系统发短信（发完短信之后可以回到App）

  1.导入MessageUI.framework，并实现代理方法MFMessageComposeViewControllerDelegate

#import<MessageUI/MessageUI.h>


- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
    [self dismissViewControllerAnimated:YES completion:nil];
    switch(result){
        caseMessageComposeResultSent:
            //信息传送成功
            break;
        caseMessageComposeResultFailed:
            //信息传送失败
            break;
        caseMessageComposeResultCancelled:
            //信息被用户取消传送
            break;
        default:
            break;
    }
}

2.发送短信

- (void)showMessageView:(NSArray*)phones title:(NSString*)title body:(NSString*)body {
    // 判断用户设备能否发送短信
    if([MFMessageComposeViewController canSendText]) {
        MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
        //收件人:phones是发短信的手机号码的数组，数组中是一个即单发,多个即群发
        controller.recipients = phones;
        //短信内容
        controller.body = body;
        controller.messageComposeDelegate = self;
        [self presentViewController:controller animated:YES completion:nil];
        //修改短信界面标题
        [[[[controllerviewControllers] lastObject] navigationItem] setTitle:title];
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示信息"
                                                     message:@"该设备不支持短信功能"
                                                    delegate:nil
                                           cancelButtonTitle:@"确定"
                                           otherButtonTitles:nil,nil];
        [alertshow];
    }
}

3.调用发短信的方法

[self showMessageView:[NSArrayarrayWithObjects:@"10086",@"10010",nil] title:@"恭喜" body:@"你们中五百万大奖啦！！"];

iOS上可以使用三种方法实现邮件的发送：

• 使用内置的MFMailComposeViewController发送邮件
  1、导入MessageUI，实现MFMailComposeViewControllerDelegate协议

 - (void)mailComposeController:(MFMailComposeViewController*)controller  
        didFinishWithResult:(MFMailComposeResult)result  
        error:(NSError*)error {  
    switch (result) 
    { 
        case MFMailComposeResultCancelled: 
            NSLog(@"Mail send canceled..."); 
            break; 
        case MFMailComposeResultSaved: 
            NSLog(@"Mail saved..."); 
            break; 
        case MFMailComposeResultSent: 
            NSLog(@"Mail sent..."); 
            break; 
        case MFMailComposeResultFailed: 
            NSLog(@"Mail send errored: %@...", [error localizedDescription]); 
            break; 
        default: 
            break; 
    } 
    [self dismissModalViewControllerAnimated:YES]; 
}

2、检测设备是否支持邮件发送功能

//检测设备是否支持邮件发送功能  
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));  
if (mailClass != nil)  
{   
    if ([mailClass canSendMail]) {  
        [self displayComposerSheet];//调用发送邮件的方法  
    }  
}

3.邮件发送方法：

- (void)sendE-mail {
    //创建视图控制器
    MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];   
    mc.mailComposeDelegate = self; 
    //设置邮件主题
    [mc setSubject:@"Hello, World!"];
    //设置收件人，收件人有三种：主收件人，cc，bcc
    [mc setToRecipients:[NSArray arrayWithObjects:@"xxx@126.com", nil];
    [mc setCcRecipients:[NSArray arrayWithObject:@"xxx@163.com"]];  
    [mc setBccRecipients:[NSArray arrayWithObject:@"xxx@gmail.com"]];   
    //设置邮件主体，有两种格式：纯文本，html格式
    [mc setMessageBody:@"Watson!!!\n\nCome here, I need you!" isHTML:NO]; 
    [mc setMessageBody:@"<HTML><B>Hello, Joe!</B><BR/>What do you know?</HTML>" isHTML:YES]; 
    //添加附件：需要三个参数，一个是NSData类型的附件，一个是mime type，一个附件的名称
    NSString *path = [[NSBundle mainBundle] pathForResource:@"blood_orange"      
      ofType:@"png"]; 
    NSData *data = [NSData dataWithContentsOfFile:path]; 
    [mc addAttachmentData:data mimeType:@"image/png" fileName:@"blood_orange"];
    //视图呈现
    [self presentModalViewController:mc animated:YES];     
}

• 通过第三方类库SKPSMTPMessage发送邮件
  1、下载三方库，导入类#import “SKPSMTPMessage.h”、#import “NSData+Base64Additions.h”，实现SKPSMTPMessage代理

//成功
- (void)messageSent:(SKPSMTPMessage *)message {
  NSLog(@"%@", message);
}

//失败
- (void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error {
  NSLog(@"message - %@\nerror - %@", message, error);
}

2、邮件发送方法

 - (void)sendE-mail {
   //设置基本参数
   SKPSMTPMessage *mail = [[SKPSMTPMessage alloc] init];
   [mail setSubject:@"主题"];  // 设置邮件主题
   [mail setToEmail:@"xxx@qq.com"]; // 目标邮箱
   [mail setFromEmail:@"xxx@qq.com"]; // 发送者邮箱
   [mail setRelayHost:@"smtp.qq.com"]; // 发送邮件代理服务器
   [mail setRequiresAuth:YES];
   [mail setLogin:@"xxx@qq.com"]; // 发送者邮箱账号
   [mail setPass:@"填你们自己的"]; // 发送者邮箱密码
   [mail setWantsSecure:YES];  // 需要加密
   [mail setDelegate:self];

   //设置邮件正文内容 
   NSString *content = [NSString stringWithCString:"邮件内容" encoding:NSUTF8StringEncoding];
   NSDictionary *plainPart = @{kSKPSMTPPartContentTypeKey : @"text/plain", kSKPSMTPPartMessageKey : content, kSKPSMTPPartContentTransferEncodingKey : @"8bit"};

   //添加附件   
   NSString *vcfPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"vcf"];
   NSData *vcfData = [NSData dataWithContentsOfFile:vcfPath];
   NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:
                             @"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.vcf\"",kSKPSMTPPartContentTypeKey,
                             @"attachment;\r\n\tfilename=\"test.vcf\"",kSKPSMTPPartContentDispositionKey,[vcfData encodeBase64ForData],kSKPSMTPPartMessageKey,
                             @"base64",kSKPSMTPPartContentTransferEncodingKey,nil];

   mail.parts = [NSArray arrayWithObjects:plainPart,vcfPart，nil];

   [mail send];
}

• 使用openURL发送邮件（用户体验较差，程序会进入后台，跳转至邮件发送界面）

- (void)sendE-mail {
   //创建可变的地址字符串对象
   NSMutableString *mailUrl = [[NSMutableString alloc] init];
   //添加收件人
   NSArray *ccRecipients = @[@"1229436624@qq.com"];
[mailUrl appendFormat:@"?cc=%@", ccRecipients[0]];
   //添加密送人
   NSArray *bccRecipients = @[@"shana_happy@126.com"];
[mailUrl appendFormat:@"&bcc=%@", bccRecipients[0]];
   //添加邮件主题和邮件内容
   [mailUrl appendString:@"&subject=my email"];
[mailUrl appendString:@"&body=<b>Hello</b> World!"];

   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailUrl]];
}
