Pass querystring parameters in AWS API Gateway iOS SDK

Question

I have set up an API Gateway for an AWS Lambda function. In the API Gateway I have setup the query string parameter and the request mapping. If I use the test function of the API Gateway I can pass the parameter to my AWS Lambda function.

I have also generated an SDK API for iOS using these instructions.

However, how can I pass my pre-defined query string parameter into this generated API class?

I have also tried using a model, however I do not see a way to pass the model data into the iOS SDK either.

If you have defined your query parameters in your API "Method Request", the SDK should be generated with the query parameters as arguments to your invocation method.

i.e.

- (AWSTask *)rootGet:(NSString *)q2 q1:(NSString *)q1 {
    NSDictionary *headerParameters = @{
                                       @"Content-Type": @"application/json",
                                       @"Accept": @"application/json",

                                       };
    NSDictionary *queryParameters = @{
                                      @"q2": q2,
                                     @"q1": q1
                                      };
    NSDictionary *pathParameters = @{

                                     };

    return [self invokeHTTPRequest:@"GET"
                         URLString:@"/"
                    pathParameters:pathParameters
                   queryParameters:queryParameters
                  headerParameters:headerParameters
                              body:nil
                     responseClass:[FOOEmpty class]];
}

Keep in mind that if you make changes to your API, the changes will need to be re-deployed to your stage before you re-generate your SDK.
