how to do a post using restkit - objective-c

Question

I am building an app using restkit to talk to my webservice. First of all I'm very new to this. What I need to do is post a username and password to my webservice so that the url looks like this.
http://urllinkcompany.com/en/webservice/company-user/login/apikey/key12345678?email=test#test.be&pwd=testtest
When I post this I get a json back. This json contains an status code. status = 200 --> OK
Status = 404 --> NOT ok
Now I tried to post something and NSLog this status code.
- (IBAction)login:(id)sender {
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Person class]];
[mapping addAttributeMappingsFromDictionary:#{
#"data.user.cu_email": #"cu_email",
}];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping pathPattern:nil keyPath:nil statusCodes:nil];
NSString *baseUrl = #"http://urllinkcompany.com/en/webservice/company-user/login/apikey/key12345678?";
NSString *strUrl = [NSString stringWithFormat:#"%#email=%#&pwd=%#",baseUrl,_txtLogin.text,_txtPass.text];
NSURL *url = [NSURL URLWithString:strUrl];
NSLog(#"url is: %#",strUrl);
NSURLRequest *request = [NSURLRequest requestWithURL:url];
RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:#[responseDescriptor]];
[operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
NSLog(#"data result is %#", [result valueForKeyPath:#"data.status"]);
} failure:nil];
}
But I am getting this error.
E restkit.network:RKObjectRequestOperation.m:285 Object request failed: Underlying HTTP request operation failed with error: Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0x1ed57c50 {NSUnderlyingError=0x20161e70 "bad URL", NSLocalizedDescription=bad URL}

Could anybody help me with this?
Kind regards

EDIT:
Here's a version without RKClient
RKObjectManager* objectManager = [RKObjectManager objectManagerWithBaseURL:[NSURL URLWithString:#"http://urllinkcompany.com/"]];
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Person class]];
[mapping addAttributeMappingsFromDictionary:#{
#"data.user.cu_email": #"cu_email",
}];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:_txtLogin.text, #"email", _txtPass.text, #"pwd", nil];
[objectManager loadObjectsAtResourcePath:#"en/webservice/company-user/login/apikey/key12345678" delegate:self block:^(RKObjectLoader* loader) {
loader.objectMapping = mapping;
loader.method = RKRequestMethodPOST;
loader.params = params;
}];
And implement those two RKObjectLoaderDelegate methods:
- (void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects
- (void)objectLoader:(RKObjectLoader *)objectLoader didFailWithError:(NSError *)error
