Bug in Parsing JSON video: Need to set self.accessToken on first login before calling refreshFoursquare

On first login (when self.accessToken is originally nil), you need to set self.accessToken equal to the newly obtained token before the call to refreshFoursquare. Otherwise, it still won't exist in the subsequent network requests in refreshFoursquare.

    if(self.accessToken == nil){
        [SimpleAuth authorize:@"foursquare-web" completion:^(id responseObject, NSError *error) {
            NSLog(@"response: %@", responseObject);
            NSString *token = responseObject[@"credentials"][@"token"];
            [defaults setObject:token forKey:@"accessToken"];
            [defaults synchronize];

            self.accessToken = token; // *** NEED TO SET TOKEN HERE
            [self refreshFoursquare];
        }];
    } else {
        [self refreshFoursquare];
    }
