Mapping to Multiple Classes in Restkit - objective-c

Question

I am using RestKit to map data to properties in two classes, Region and Category, for use in two table views, Regions and Categories. However, it would appear that it is only correctly mapping data for the first view that I go to when testing the application. For instance, when I view Categories first, then switch the Regions, my regions are getting stored as objects of type Category. If I view Regions first, then Categories, my categories get mapped as objects of type Region. I can tell that the right information is being retrieved, due the number of objects, but it is not being stored as the correct type. How can I make sure that each mapping request is done correctly? The code for each mapping is below:
Categories:
RKURL *baseURL = [RKURL URLWithBaseURLString:#"MyUrl"];
RKObjectManager *objectManager = [RKObjectManager objectManagerWithBaseURL:baseURL];
objectManager.client.baseURL = baseURL;
RKObjectMapping *categoryMapping = [RKObjectMapping mappingForClass:[Category class]];
[categoryMapping mapKeyPathsToAttributes:#"categoryID", #"categoryID", #"parentID", #"parentID", #"categoryName", #"categoryName", #"childrenCount", #"childrenCount", #"parentCount", #"parentCount", #"catCount", #"catCount", nil];
[objectManager.mappingProvider setMapping:categoryMapping forKeyPath:#""];
Regions:
RKURL *baseURL = [RKURL URLWithBaseURLString:#"MyUrl"];
RKObjectManager *objectManager = [RKObjectManager objectManagerWithBaseURL:baseURL];
objectManager.client.baseURL = baseURL;
NSLog(#"URL Created");
RKObjectMapping *regionMapping = [RKObjectMapping mappingForClass:[Region class]];
[regionMapping mapKeyPathsToAttributes:#"regionHome", #"regionHome", #"regionID", #"regionID", #"regionName", #"regionName", #"parentCount", #"parentCount", #"parentID", #"parentID", #"childrenCount", #"childrenCount", #"parentName", #"parentName", nil];
[objectManager.mappingProvider setMapping:regionMapping forKeyPath:#""];

In my judgment you don't want to leave the key path as #"" in [objectManager.mappingProvider setMapping:regionMapping forKeyPath:#""];. You will probably replace those with #"region" and #"category" so RestKit can tell based on the key path what objects it should expect.
Also, are you using the isKindOfClass: method to distinguish the objects in the objectLoader didLoadObjects method?
Perhaps this will help you:
- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects {
if ([[objects objectAtIndex:0] isKindOfClass:[Region class]]) {
Region *region = [objects objectAtIndex:0];
}
else if ([[objects objectAtIndex:0] isKindOfClass:[Category class]]) {
Category *category = [objects objectAtIndex:0];
}
}
