Hook your own button into "share list" for iOS?

When you take a picture or look at one in the album, there is a "share-button" visible. Is it possible to hook-in your own item to that list, so I can share the picture via my o开发者_如何学运维wn app? If so, how do I do that?

There's an answer to this for Android, but I couldn't find this for iOS: Hook in your own item to the "share-list"

There are no built-in classes that do this on iOS, but I suggest you try ShareKit. It is a joy to work with!

You can register the fact that your app can open files of particular types, for more information here are Apple's docs about registering your app and how to open the files.

This is available from iOS 3.2 onwards
