title: Can't logon as Facebook test account on iOS Simulator
body: <p>I have a Facebook app with 10 test users. I am developing an iOS app and have setup up the plist file with the Facebook app id as described in the docs.</p>
  
  <p>I run my app in iOS Simulator and click my Facebook Login button which takes me to the Facebook web app. I try to login with one of my Facebook app's test user and I get the error below.</p>
  
  <p>I've seen Facebook Developer videos where the presenter logs on to the Facebook web app from the iOS Simulator. Do you know why I can't?</p>
  
  <p>Thanks</p>
