Restkit object mappings not working - objective-c

Question

I am trying to learn restkit and right now and working on object mappings. Here is the JSON that I am trying to receive and process (generated by ASP.NET MVC Web API):
[
{
"Id": 0,
"Title": "Test",
"Location": "Test",
"Score": {
"Hill": 10,
"LVille": 12
},
"TimeStart": "2012-11-10T12:30:00",
"TimeEnd": "2012-11-10T13:20:00",
"Gender": 0,
"State": 0
},
{
"Id": 0,
"Title": "ee",
"Location": "12:00",
"Score": {
"Hill": 13,
"LVille": 0
},
"TimeStart": "12:00 PM",
"TimeEnd": "12:00 PM",
"Gender": 1,
"State": 1
}
]
The objects that are being mapped to are (SBGame):
#interface SBGame : NSObject
#property (nonatomic, copy) NSNumber* Id;
#property (nonatomic, copy) NSString* Title;
#property (nonatomic, copy) NSString* Location;
#property (nonatomic, strong) SBScore* Score;
#property (nonatomic, copy) NSString* TimeStart;
#property (nonatomic, copy) NSString* TimeEnd;
#property (nonatomic, copy) NSNumber* Gender;
#property (nonatomic, copy) NSNumber* State;
#end
and SBScore :
#interface SBScore : NSObject
#property (nonatomic, copy) NSNumber* Hill;
#property (nonatomic, copy) NSNumber* LVille;
#end
and last but not least the object mappings
RKObjectMapping *ScoreMapping = [RKObjectMapping mappingForClass:[SBScore class]];
[ScoreMapping addAttributeMappingsFromArray:#[#"Hill", #"LVille"]];
RKObjectMapping *GameMapping = [RKObjectMapping mappingForClass:[SBGame class]];
[GameMapping addAttributeMappingsFromDictionary:#{
#"Id" : #"Id",
#"Title" : #"Title",
#"Location" : #"Location",
#"TimeStart" : #"TimeStart",
#"TimeEnd" : #"TimeEnd",
#"Gender" : #"Gender",
#"State" : #"State",
}];
[GameMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:#"score" toKeyPath:#"score" withMapping:ScoreMapping]];
RKResponseDescriptor *decp = [RKResponseDescriptor responseDescriptorWithMapping:GameMapping pathPattern:#"/Games" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[objectManager addResponseDescriptor:decp];
after all that the error that I recieve is
2012-12-29 16:49:19.553 Scoreboard[3004:c07] Failure with error Error Domain=org.restkit.RestKit.ErrorDomain Code=1001
"Unable to find any mappings for the given content" UserInfo=0x75c1460 {DetailedErrors=(
), NSLocalizedDescription=Unable to find any mappings for the given content, keyPath=null}
I am very new to RestKit and I have looked through The Object Mapping Tutorial but still it does not work. Any ideas are much appreciated.

Answer 1

I figured it out. When I created the default instance I made the base URL www.example.com/api and then just made the binding and the getObjects method to /Games
What I should have done is made the base URL www.example.com set the path pattern to /api/Games and call the getObjects method on /api/games
So from the code shown
RKResponseDescriptor *decp
= [RKResponseDescriptor responseDescriptorWithMapping:GameMapping
pathPattern:#"/Games"
keyPath:nil
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
changes to
RKResponseDescriptor *decp
= [RKResponseDescriptor responseDescriptorWithMapping:GameMapping
pathPattern:#"/api/Games"
keyPath:nil
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
