RestKit Object mapping issue - ios

Question

I have this JSON response that I can't figure out how to map. It looks like this:
{
"responseError": null,
"displayMenuList": {
"MenuList": [
{
"ID": "3223",
"Name": "Main",
"AddressURL": "www.mysite.com",
"DisplayType": "True",
"ImageURL": "main.png",
"NotSplitBUser": "True",
"ParentCategoryId": "3223",
"PrivateUser": "True",
"SortOrder": 1,
"SplitBUser": "True",
"TargetURL": "_self"
},
{
"ID": "3307",
"Name": "Contact",
"AddressURL": "www.mysite.com",
"DisplayType": "True",
"ImageURL": "service.png",
"NotSplitBUser": "True",
"ParentCategoryId": "3224",
"PrivateUser": "True",
"SortOrder": 0,
"SplitBUser": "True",
"TargetURL": "_self"
},
{
"ID": "3298",
"Name": "Call Us",
"AddressURL": "www.mysite.com",
"DisplayType": "True",
"ImageURL": "service.png",
"NotSplitBUser": "True",
"ParentCategoryId": "3224",
"PrivateUser": "True",
"SortOrder": 1,
"SplitBUser": "True",
"TargetURL": "_self"
},
{
"ID": "3224",
"Name": "Service",
"AddressURL": "www.mysite.com",
"DisplayType": "True",
"ImageURL": "service.png",
"NotSplitBUser": "True",
"ParentCategoryId": "3224",
"PrivateUser": "True",
"SortOrder": 2,
"SplitBUser": "True",
"TargetURL": "_self"
}
]
},
"responseCurrentBillState": null,
"responseGetPcrfSubBuckets": null,
"userData": {
"abroadInd": null,
"accountType": "B",
"customerId": "",
"fullName": "Juan",
"subscriberNumber": ""
}
}
I just can't figure out how to map those objects, I've created object called RKSideMenu, also an object called RKUserData they look like this:
#interface RKSideMenu : NSObject
#property (copy, nonatomic) NSString *addressURL;
#property (copy, nonatomic) NSString *displayType;
#property (copy, nonatomic) NSNumber *id_number;
#property (copy, nonatomic) NSString *imageURL;
#property (copy, nonatomic) NSString *name;
#property (assign, nonatomic) BOOL splitBUser;
+ (NSDictionary*)getAttributes;
#end
#implementation RKSideMenu
+ (NSDictionary*)getAttributes
{
return [NSDictionary dictionaryWithObjects:#[#"addressURL", #"displayType", #"id_number", #"imageURL", #"name", #"splitBUser"]
forKeys:#[#"AddressURL", #"DisplayType", #"ID", #"ImageURL", #"Name", #"SplitBUser"]];
}
#end
#interface RKUserData : NSObject
#property (copy, nonatomic) NSString *abroadInd;
#property (copy, nonatomic) NSString *accountType;
#property (copy, nonatomic) NSString *customerID;
#property (copy, nonatomic) NSString *fullName;
#property (copy, nonatomic) NSString *subscriberNumber;
+ (NSDictionary*)getAttributes;
#end
#implementation RKUserData
+ (NSDictionary*)getAttributes
{
return [NSDictionary dictionaryWithObjects:#[#"abroadInd", #"accountType", #"customerID", #"fullName;", #"subscriberNumber"]
forKeys:#[#"abroadInd", #"accountType", #"customerId", #"fullName;", #"subscriberNumber"]];
}
#end
I started mapping with those two methods, but than I stuck and don't know what to do. I look at https://github.com/RestKit/RestKit/wiki/Object-mapping, but still couldn't get it right.
RKObjectMapping *sideMenuMapping = [RKObjectMapping mappingForClass:[RKSideMenu class]];
[sideMenuMapping addAttributeMappingsFromDictionary:[RKSideMenu getAttributes]];
RKObjectMapping *userDataMapping = [RKObjectMapping mappingForClass:[RKUserData class]];
[userDataMapping addAttributeMappingsFromDictionary:[RKUserData getAttributes]];
Thanks in advance!
Edit: Json on top replaced with real json from server.

Answer 1

So what you need to do in order to setup your mapping is first of all define the base url of your API, like so:
AFHTTPClient *client = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:#"URL_TO_YOUR_API"]];
RKObjectManager *objectManager = [[RKObjectManager alloc] initWithHTTPClient:client];
Then you need to set a response descriptor for the url that outputs the json above:
[[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:sideMenuMapping
method:RKRequestMethodAny
pathPattern:#"/mainScreenData"
keyPath:#"displayMenuList.MenuList"
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];
"RKRequestMethodAny" should be replaced by the Request Method you are using e.g. "RKRequestMethodGET".
Then you just retrieve the objects by calling:
[[RKObjectManager sharedManager] getObjectsAtPath:#"/mainScreenData"
parameters:nil
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSArray *sideMenuList = [NSMutableArray arrayWithArray:[mappingResult array]];
}
failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"%#",[error localizedDescription]);
}];
I would highly recommend you having a look at the demos that are supplied by RestKit. That makes the whole process a lot clearer.
