I have been struggling with this problem for some time now, I want to simply share a photo with description to facebook using facebook sdk4.1. I can share a photo easily using SharePhotoContent object.
but it doesn't add description to the photo, so I searched for solutions and it seems that Open graph stories are one solution but it requires much work than this requirement deserve.
Although I tried to find a way to use Open Graph Stories but it requires an action for the story and the available ones doesn't go with my app, so I tried to search for a way to create custom actions but I couldn't.
So please help me with another solution for using open graph stories or provide any tutorial link.
You can Publish Story with Share Dialog through this and also read how Sharing Open Graph Stories from here hope it work for you.
To create and configure custom actions and custom objects for stories try this and this.
Best of Luck.
