On iOS devices, the Mail app offers "Open In..." option for attachments. The apps listed have registered their CFBundleDocumentTypes with the OS. What I am wondering is how my app might allow users to open files generated by my app in other apps. Is Mail the only app that provides this feature?

Take a look at the Device Features Programming Guide.
As long as you provide your document types in your Info.plist, other apps that recognize that document type will list your app in their "open in" choices. Of course, that presumes that your app creates documents that other apps can open.

Thanks! That looks like exactly what I was searching for. And, yes, my app creates .csv and .zip files.
