Question

But after adding AdColony in app.

Facebook login not working. Below code for Facebook login

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior=FBSDKLoginBehaviorSystemAccount;

[login logInWithReadPermissions:@[@"email",@"public_profile",@"user_friends"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
    if (error) {
        NSLog(@"Process error %@",result);

    }
    else if (result.isCancelled)
        }
    else {

    }
