How to change language in Facebook login page or dialog?

Question

I have a problem for a long time, I don't figure out where the problem is. My own app and this Hackbook Demo app have the same situation when auth dialog popup. No matter web dialog or Faccbook native app, I'd like it to show in English. Even, my ios language is English, the auth dialog is still not in English.

somebody help me, please, thanks!

Its a Facebook-level issue. check this :

the problem is :

"On initial login using Facebook, the dialog asking the user to authorize this application is displayed in seemingly random languages.. Only Happens when user is connected over Wifi."
