使用MFMailComposer发送CSV文件

Question

我想使用带有.csv扩展名的NSString(已经制作)创建一个文件,然后使用UIMessage框架通过电子邮件发送它.那么有人可以告诉我创建文件的代码(带有.csv扩展名和NSString的内容)然后如何将它附加到MFMailComposeViewController.

Answer 1

这是将CSV文件附加到MFMailComposeViewController的方法:

    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. 

至于如何生成CSV文件本身,https://github.com/davedelong/CHCSVParser上的CHCSVWriter类 将为您提供帮助.
