使用MFMailComposer通过电子邮件发送CSV文件 [英] Email CSV file with MFMailComposer

问题描述

我想使用扩展名为.csv的NSString(已制成)创建文件，然后使用UIMessage框架通过电子邮件发送该文件.有人可以向我展示代码来创建文件(具有.csv扩展名和NSString的内容)，然后将其附加到MFMailComposeViewController的代码.

I would like to create a file using a NSString (already made) with a .csv extension then email it using the UIMessage framework. So can someone show me the code to create a file (with a .csv extensions and with the contents of a NSString) then how to attach it to a MFMailComposeViewController.

推荐答案

这是将CSV文件附加到MFMailComposeViewController的方法:

This is how you attach a CSV file to a MFMailComposeViewController:

    MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
    mailer.mailComposeDelegate = self;
    [mailer setSubject:@"CSV File"];        
    [mailer addAttachmentData:[NSData dataWithContentsOfFile:@"PathToFile.csv"]
                     mimeType:@"text/csv" 
                     fileName:@"FileName.csv"];
    [self presentModalViewController:mailer animated:YES];

    // Note: PathToFile.csv is the actual path of the file on your iOS device's 
    // file system. FileName.csv is what it should be displayed as in the email.
