I have a basic Cocoa application that allows users to edit text documents containing images using the integrated WebView (via <div contenteditable="true">...</div> ).
This is very similar to composing a message in Mail (there is also a WebView in the editor used).
Like Mail, I would like to open the markup action extension inside my application so that users can add markup to images right in my application.
After watching the “Create Extensions” videos from WWDC 2014, I’m still not sure if it’s possible to expose actions extensions from a user view (something like a sharing tool).
In the second part of the WWDC video, they note that NSTextView has built-in support for action extensions, but what if I need to expose action extensions through a custom view?
Here is an example of what it looks like in Mail:
