RestKit iOS - Second Time fails - restkit

Question

I'm using the RestKit for a simple request that returns JSON data.
I've implemented this code that works only the first time that the viewDidLoad is called, the second time the request is not performed. Why??
- (void)viewDidLoad
{
[super viewDidLoad];
[self planOtpTrip];
}
-(void) planOtpTrip{
NSLog(#"[INFO] planoOtpTrip");
client = [RKClient clientWithBaseURLString:#"http://myserver/opentripplanner-api-webapp/ws"];
[client setValue:#"application/json" forHTTPHeaderField:#"Accept"];
NSDictionary *queryParameters = [NSDictionary dictionaryWithObjectsAndKeys:#"45.028952,7.624598",#"fromPlace",#"45.06123,7.65981", #"toPlace",#"TRANSIT,WALK" ,#"mode", nil];
// Imposto il nome della API da richiamare
NSString *getResourcePath = RKPathAppendQueryParams(#"/plan", queryParameters);
[client get:getResourcePath delegate:self];
}
- (void)request:(RKRequest*)request didLoadResponse:(RKResponse*)response {
// where you handle response object
NSLog(#"Risposta ricevuta: %#", response.URL);
NSLog(#"Response Body: %#", response.bodyAsString);
id jsonParser = [[RKParserRegistry sharedRegistry] parserForMIMEType:RKMIMETypeJSON];
NSError *error = nil;
NSDictionary* parsedResponse = [jsonParser objectFromString:[response bodyAsString] error:&error];
if (error == nil)
{
NSLog(#"GET returned with HTTP Code %d and parsedContent: %#", [response statusCode], parsedResponse);
}
else
{
NSLog(#"Error: %#", error);
}
return [self renderResponse:parsedResponse];
}

I had this problem as well but i found a solution. Define the RKClient in your .h file like so:
#property (retain) RKClient *downloadClient;
Then in your .m file synthesize the downloadClient like so:
#synthesize downloadClient;
And then in your didLoadResponse method you release the downloadClient when your done with it, like so:
- (void)request:(RKRequest*)request didLoadResponse:(RKResponse*)response
{
//do something with your response
[downloadClient release];
}
