1.加入邮箱的框架

#import <MessageUI/MFMailComposeViewController.h>
#import <MessageUI/MessageUI.h>

2.添加委托

@interface ViewController : UIViewController<MFMailComposeViewControllerDelegate>

3.实现代码

- (void)alertWithTitle:(NSString *)title  msg:(NSString *)msg
{
    if (title && msg)
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:msg
                                                       delegate:nil
                                              cancelButtonTitle:@"确定"
                                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }

}

- (IBAction)OnButtonWriteLog:(id)sender
{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy_MM_dd_HH_mm"];  // 设置格式为年-月-日 时:分:秒:毫秒

    NSString *timeStr = [dateFormatter stringFromDate:[NSDate date]];
    [dateFormatter release];


    NSArray *userPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *filePackageName = [userPaths objectAtIndex:0];


    NSString* fileNamePackageRes = [[NSString alloc] initWithFormat:@"%@/%@_%@",filePackageName,timeStr,@"log.txt"];


    NSString* strLogData = [[NSString alloc]initWithFormat:@"my is log time:%@",timeStr];
    [strLogData writeToFile:fileNamePackageRes atomically:NO encoding:NSUTF8StringEncoding error:nil];


    [_logName release];
    _logName = [[NSString alloc ]initWithString:fileNamePackageRes];

    [fileNamePackageRes release];

    [self alertWithTitle:@"提示" msg:@"写入成功"];
}



- (IBAction)OnButtonSendMailToMe:(id)sender {

    NSString *logData = [[NSString alloc]initWithContentsOfFile:_logName encoding:NSUTF8StringEncoding error:nil];
    if (logData)
    {

        if(mailCompose)
        {
            //设置代理
            [mailCompose setMailComposeDelegate:self];

            NSArray *toAddress = [NSArray arrayWithObject:@"98zg@sina.cn"];
            NSArray *ccAddress = [NSArray arrayWithObject:@"17333245@qq.com"];;
            NSString *emailBody = @"<H1>日志信息</H1>";

            //设置收件人
            [mailCompose setToRecipients:toAddress];
            //设置抄送人
            [mailCompose setCcRecipients:ccAddress];
            //设置邮件内容
            [mailCompose setMessageBody:emailBody isHTML:YES];

            NSData* pData = [[NSData alloc]initWithContentsOfFile:_logName];

            //设置邮件主题
            [mailCompose setSubject:@"这里是主题"];
            //设置邮件附件{mimeType:文件格式|fileName:文件名}
            [mailCompose addAttachmentData:pData mimeType:@"txt" fileName:@"日志.txt"];
            //设置邮件视图在当前视图上显示方式
            [self presentModalViewController:mailCompose animated:YES];
        }
        [mailCompose release];

        return;
    }


    [logData release];


    [self alertWithTitle:@"提示" msg:@"请先点击写入日志按钮"];
}


- (void)dealloc
{
    [_logName release];
    [super dealloc];
}

    NSString *msg;

    switch (result)

            msg = @"邮件发送取消";
            break;
