Does anyone know how message.framework and mime.framework?

I need for my iPad app, that will not be send to AppStore because it is only for personal use, these private frameworks for send an email with inline image (image inside of my app that I 开发者_StackOverflow中文版can't upload to a server). I was able to successfully import them but now I really don't know how to use them. My big problem is how to connect message to my MFMailComposeViewController? Thanks in advance

You don't need to use private frameworks to attach an image to an email. MFMailComposeViewController has the -addAttachmentData:mimeType:fileName: method which will allow you to attach an image or any other file.
