使用`MFMailComposeViewController`发送邮件。  
1、导入头文件

#import <MessageUI/MessageUI.h>

2、实现`MFMailComposeViewControllerDelegate`代理方法  
3、示例

// 判断用户是否已设置邮件账户
    if ([MFMailComposeViewController canSendMail]) {
            // 弹出邮件发送视图
            MFMailComposeViewController *emailVC = [[MFMailComposeViewController alloc] init];
            // 设置邮件代理
            [emailVC setMailComposeDelegate:self];
            // 设置收件人
            [emailVC setToRecipients:@[kEmail]];
            // 设置抄送人
            // [_emailVC setCcRecipients:@[@"10000@qq.com"]];
            // 设置密送人
            // [_emailVC setBccRecipients:@[@"10000@163.com"]];
            // 设置邮件主题
            [emailVC setSubject:@"意见反馈【二维码识别】"];
            //设置邮件的正文内容
            NSString *emailContent = @"邮件内容: ";
            // 是否为HTML格式
            [emailVC setMessageBody:emailContent isHTML:NO];
            // 如使用HTML格式，则为以下代码
            // [mailCompose setMessageBody:@"<html><body><p>Hello</p><p>World！</p></body></html>" isHTML:YES];
            // 添加附件
            // UIImage *image = [UIImage imageNamed:@"qq"];
            // NSData *imageData = UIImagePNGRepresentation(image);
            // [mailCompose addAttachmentData:imageData mimeType:@"" fileName:@"qq.png"];
            // NSString *file = [[NSBundle mainBundle] pathForResource:@"EmptyPDF" ofType:@"pdf"];
            // NSData *pdf = [NSData dataWithContentsOfFile:file];
            // [mailCompose addAttachmentData:pdf mimeType:@"" fileName:@"EmptyPDF.pdf"];
            [self presentViewController:emailVC animated:YES completion:nil];
        } else {
            // 给出提示,设备未开启邮件服务
            InsertAlert(UIAlertViewStyleDefault, @"没有邮件帐户", @"请添加邮件帐户（添加方法：设置->邮件、通讯录、日历->添加帐户->其他->添加邮件帐户）", 0, nil, nil, kAlertRealized);
    }

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