Clue ...

addAttachmentData:NULL

You need to actually attach the data. The filename is just the name you are choosing to give the file, it has no other use and doesn't mean attach the file with that name.

The MFMailComposeViewController documentation makes it clear.

You therefore need to do something like this;

NSData *myData = [NSData dataWithContentsOfFile:your-full-file-path];

To generate the data. Note you need to give the full filepath, not just the name (left as an exercise for the reader).
