title: AFNetworking 2.0: Passing header information
body: <p>I am new to AFNetworking and I know how to pass URL parameters. But how would I pass headers into the same call. </p>
  
  <p>I am also subclassing my AFHTTPSessionManager</p>
  
  <p>See my code below:</p>
  
  <pre><code>- (void)getExpenses:(NSString *)page
                  success:(void (^) (NSArray *myExpenses))success
                  failure:(RequestFailureBlock)failure
  {
      NSString *resourceURL = [NSString stringWithFormat:@"%@/expenses/", APIBaseURLString];
      NSDictionary *parameters = @{@"page":page, @"Authorization": APIAuthorization};
  
      [self getExpenses:resourceURL parameters:parameters success:success failure:failure];
  
  }
  </code></pre>
