I just need to post some text and Image on the Facebook wall of my app's user. The Facebook app registered in developers.facebook.com doesn't have "publish_actions" permission by default. I already have submitted request for this permission but its taking long to get approved. Meanwhile seeing my friend doing this post operation thorugh ios app without this "publish_action" permission I am curious do i need this permission to post some text and image on users wall at all? Please help me..
You dont, if you are using open graph:
Reference: The Share dialog lets people publish stories from your app without Facebook Login or the publish_actions permission. However you still have to send your app for review.
The best part is that a user can tag people in a post built upon graph API. As a sample app I would suggest you check how Scrumptious works, it comes prepackaged in the FB SDK.
