Ios facebook sdk error systemlogincancelled

I am getting facebook sdk error on ios when trying to login - note that I just updated my facebook sdk version to 3.21.1. Interestingly, it works great on a simulator. When I login to facebook on my iphone under settings => facebook, the facebook login in my app fails, but when I disable my facebook login it works fine again.

Here is my code:

NSArray * basicPermissions = @[@"public_profile", @"user_friends", @"email"];
[FBSession openActiveSessionWithReadPermissions:basicPermissions allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {

    [DCTLogger debug:@"facebookLoginQ:Callback: %@/%p sess=%@ ", [DCTBase stringForFBSessionState:status], error, session];
    if (error) {
        dispatch_async(q, ^{
            handlerCopy(nil, error);
        });

        return;
    }

    if (status == FBSessionStateOpen) {
        [FBSession setActiveSession:session];
        [self facebookSessionCreatedQ:q Callback:handlerCopy];
    }
}];

      

        
        
        
      

    

The error I am getting is com.facebook.sdk:ErrorLoginFailedReason=com.facebook.sdk:SystemLoginCancelled

with facebook sdk error code 2.

Another interesting point is that if I remove public_profile

from basicPermissions

, the input is fine, and like the other post, I've seen this if I use a deprecated method openActiveSessionWithPermissions

and not openActiveSessionWithReadPermissions

it works great.

Just want to point out again that it only seems unsuccessful if there is a registered facebook account on the device. I feel like maybe the new sdk includes automatically public_profile

, so if I ask for it again in basicPermissions it will cause a problem.
