title: FB.AppRequest Crash
body: <p>So I'm not sure if this is an issue with Unity or with the Facebook Unity SDK, or something I might be doing? It only started appearing recently, it was working perfectly fine up until I had to update Unity for iOS9 font issues.</p>
  
  <p>The point at which it crashes in Xcode is:</p>
  
  <pre><code>+ (instancetype)instanceWithRequestID:(int)requestID
  {
      FBUnitySDKDelegate *instance = [[FBUnitySDKDelegate alloc] init];
      instance-&gt;_requestID = requestID;
      [g_instances addObject:instance];  // Breaks on this line. instance is nil
      return instance;
  }
  </code></pre>
  
  <p>And the code I am using for the AppRequest is</p>
  
  <pre><code>public void RequestLivesFromFriends(string[] friendIds)
  {
      if(!FB.IsLoggedIn)
      {
          LoginToFacebook ();
          return;
      }
      FB.AppRequest(
          "Please send me a life!",
          Facebook.Unity.OGActionType.ASKFOR,
          livesIdValue,
          friendIds,
          "RequestLife",
          "Request a life from your friends",
          requestLifeCallback
          );
  }
  </code></pre>
  
  <p>Is there currently an issue with the SDK's? Or am I just doing something wrong?</p>
