How to attach a file of any types to the Email in iOS

Question

I am interpreting a function onto my iOS App to attach an original data on the Email as a file. The app is a movie composer.

The data format is written as XML and I want the app to attach the data on the Email as the file with an original extension (.kpt). Besides, I want the receiver to open the received XML file using the movie composer.

The question is the following:

How to let the app to attach the original data to the email with an original extension?

How to setup an attachment:

MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];
[mailController setSubject:@"Some Subject"];
[mailController addAttachmentData:data
                         mimeType:@"application/kpt"
                         fileName:@"originalFileName.kpt"];

In order to open the file inside your app, you will need to modify your Info.plist to describe a new document UTI. The programming guide for doing this can be found here.
