How to attach files to UIActivityTypeMail?

Question

I like to share files (images, videos, pdf, plist, txt…) with UIActivityViewController, I am trying to share a NSData object, but it wont work. If I replace the NSData with UIImage it works.

Is it possible to add this to the UIActivityViewController: [mailer addAttachmentData:imageData mimeType:[[self.filePath lastPathComponent] pathExtension] fileName:[self.filePath lastPathComponent]];

Answer 1

If you want to attach raw data you should use an appropriate mime type, like

application/octet-stream

And preferably set an appropriate file name and extension (like .bin )

Try this to determine the mime type for files.
