APP内发送邮件的功能用的不是特别多，但是有些情况下还是需要的，最近用到了，拿来分享一下。

一、引用头文件库：

#import <MessageUI/MFMailComposeViewController.h>

实现MFMailComposeViewControllerDelegate 的方法。

二、代码实现

- (void)sendByEmail{

    MFMailComposeViewController *mailSender = [[MFMailComposeViewController alloc]init];    

mailSender.mailComposeDelegate = self;    

[mailSender setSubject:@""];   

 [mailSender setMessageBody:@""  isHTML:NO];    

[mailSender setToRecipients:[NSArray arrayWithObjects:@"xxx@163.com", nil]];

[mailSender addAttachmentData:datamimeType:mimeTypefileName:fileName];   

    [self presentViewController:mailSender animated:YES completion:^{

        //

    }];

}

#pragma mark - MFMailComposeViewControllerDelegate

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error

{

    [controller dismissViewControllerAnimated:YES completion:nil];

    switch(result) {

        case MFMailComposeResultCancelled:

        {

            [SVProgressHUD showInfoWithStatus:@"发送取消"];

        }

            break;

        case MFMailComposeResultSaved:

        {

            [SVProgressHUD showInfoWithStatus:@"存储成功"];

        }

            break;

        case MFMailComposeResultSent:

        {

            [SVProgressHUD showInfoWithStatus:@"发送成功"];

        }

            break;

        case MFMailComposeResultFailed:

        {

             [SVProgressHUD showInfoWithStatus:@"发送失败"];

        }

            break;

    }

}
