NSArray *ccRecipients = @[@"1229436624@qq.com"];[mailUrl appendFormat:@"?cc=%@", ccRecipients[0]];

NSArray *bccRecipients = @[@"shana_happy@126.com"];[mailUrl appendFormat:@"&bcc=%@", bccRecipients[0]];

二、使用MFMailComposeViewController发送邮件(原生)

使用前注意：

1）项目需要导入框架：MessageUI.framework

2）使用的Controlelr里导入头文件：#import <MessageUI/MessageUI.h>

获取用户是否设置了邮件账户：

if ([MFMailComposeViewController canSendMail]) { // 用户已设置邮件账户    [self sendEmailAction]; // 调用发送邮件的代码}

sendEmailAction方法代码：

- (void)sendEmailAction{  // 邮件服务器  MFMailComposeViewController *mailCompose = [[MFMailComposeViewController alloc] init];  // 设置邮件代理  [mailCompose setMailComposeDelegate:self];  // 设置邮件主题  [mailCompose setSubject:@"我是邮件主题"];  // 设置收件人  [mailCompose setToRecipients:@[@"1147626297@qq.com"]];  // 设置抄送人  [mailCompose setCcRecipients:@[@"1229436624@qq.com"]];  // 设置密抄送  [mailCompose setBccRecipients:@[@"shana_happy@126.com"]];  /**   *  设置邮件的正文内容   */  NSString *emailContent = @"我是邮件内容";  // 是否为HTML格式  [mailCompose setMessageBody:emailContent isHTML:NO];  // 如使用HTML格式，则为以下代码//	[mailCompose setMessageBody:@"
Hello
World！
" isHTML:YES];  /**   *  添加附件   */  UIImage *image = [UIImage imageNamed:@"image"];  NSData *imageData = UIImagePNGRepresentation(image);  [mailCompose addAttachmentData:imageData mimeType:@"" fileName:@"custom.png"];  NSString *file = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"];  NSData *pdf = [NSData dataWithContentsOfFile:file];  [mailCompose addAttachmentData:pdf mimeType:@"" fileName:@"dddddd"];  // 弹出邮件发送视图  [self presentViewController:mailCompose animated:YES completion:nil];}

MFMailComposeViewControllerDelegate的代理方法：

- (void)mailComposeController:(MFMailComposeViewController *)controller      didFinishWithResult:(MFMailComposeResult)result            error:(NSError *)error{  switch (result)  {    case MFMailComposeResultCancelled: // 用户取消编辑      NSLog(@"Mail send canceled...");      break;    case MFMailComposeResultSaved: // 用户保存邮件      NSLog(@"Mail saved...");      break;    case MFMailComposeResultSent: // 用户点击发送      NSLog(@"Mail sent...");      break;    case MFMailComposeResultFailed: // 用户尝试保存或发送邮件失败      NSLog(@"Mail send errored: %@...", [error localizedDescription]);      break;  }  // 关闭邮件发送视图  [self dismissViewControllerAnimated:YES completion:nil];}

三、 使用第三方库SKPSMTPMessage发送邮件

使用前注意：

1）下载第三方库

2）导入类#import "SKPSMTPMessage.h"、#import "NSData+Base64Additions.h"

设置基本参数：

SKPSMTPMessage *mail = [[SKPSMTPMessage alloc] init];[mail setSubject:@"我是主题"];  // 设置邮件主题[mail setToEmail:@"填你们自己的@qq.com"]; // 目标邮箱[mail setFromEmail:@"填你们自己的@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:@"填你们自己的@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:"测试内容" encoding:NSUTF8StringEncoding];NSDictionary *plainPart = @{kSKPSMTPPartContentTypeKey : @"text/plain", kSKPSMTPPartMessageKey : content, kSKPSMTPPartContentTransferEncodingKey : @"8bit"};

添加附件（以下代码可在SKPSMTPMessage库的DMEO里找到）：

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];

执行发送邮件代码：

[mail setParts:@[plainPart, vcfPart]]; // 邮件首部字段、邮件内容格式和传输编码[mail send];

SKPSMTPMessage代理，可以获知成功/失败进行后续步骤处理：

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

UIWebView *webView = [[UIWebViewalloc] initWithFrame:CGRectZero];

NSURL *url = [NSURLURLWithString:@"mqq://im/chat?chat_type=wpa&uin=QQ号&version=1&src_type=web"];//这里的QQ号是我要联系的对方qq号码

NSURLRequest *request = [NSURLRequestrequestWithURL:url];

     webView.delegate = self;

[webView loadRequest:request];

[self.view addSubview:webView];
