我遇到了AFNetworking的问题.我无法设置content-type到application/json.我能怎么做？我尝试了很多解决方案,但没有人工作过.这是你的代码:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
  if (self.enableBasicAuth){
    [manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:[[SOWMerchant merchant]     username] password:[[SOWMerchant merchant] password]];
  }
  [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
  manager.responseSerializer = [AFJSONResponseSerializer serializer];
  [manager POST:[NSString stringWithFormat:@"%@", url] parameters:postData success:^(AFHTTPRequestOperation *operation, id responseObject) {
    [self onSuccessResponse:responseObject request:operation];
  } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    [self onError:error request:operation];
  }];
