ios - Facebook SDK 3.6 Open Graph Error Message -

-

im trying use new share dialog , works fine when facebook app not installed , im sharing own viewcontroller:

if (!call) {         // fallback customized share ui         myshareviewcontroller *viewcontroller = [[myshareviewcontroller alloc] initwithitem:object                                                                                  objecttype:@"objecttype"                                                                                  actiontype:@"namespace:action"];         [_delegate showfallbacksharedialog:viewcontroller];      }

so code gets called when facebook app isnt installed. when installed device opens facebook app , here user can type message included in open graph action

enter image description here

but after few second devices switches app , error shows up:

error: error domain=com.facebook.facebook.platform code=102 "the operation couldn’t completed. (com.facebook.facebook.platform error 102.)" userinfo=xxxx {error_code=102, action_id=xxx-xxx-xxx-xxx-xxx, error_message=could not generate preview text, app_id=xxxxx}

i've been searching web explanation can't find whats wrong. know error means?

edit notice greyed out "post" button.

check following

  1. facebookdisplayname set , correct in plist's url scheme
  2. fbxxxxxxxxxxx added in plist file
  3. facebookappid set correctly in plist file
  4. in status & review section make sure have "do want make app , live features available general public?" make yes (by default it's no)
