I use Facebook iOS SDK 3.1 in my last one, and I use the native common dialog with FBNativeDialogue .

In the corner there is a βfriendsβ button in which I have always been attached to friends (just like the location button indicates the location), but I realized that these are the privacy settings for the message.
So Im still confusing how you can tag friends in a post. Nothing seems to happen when I type @ and then the names of my friends, is this not yet implemented? And does anyone know a smart way to implement this?
What the customer wants is similar to βWho are you?β, As shown below:
