Question

I used RestKit to load XML data from a resource. That worked perfect, but now I want to change my whole program to read local XML files. I found the possibility to read a local xml file and parse it through RestKit in the Google RestKit Group:

NSString *string = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"testing" ofType:@"xml"] encoding:NSUTF8StringEncoding error:nil]; 
id<RKParser> parser = [[RKParserRegistry sharedRegistry] parserForMIMEType:RKMIMETypeXML]; 
id result = [parser objectFromString:string error:nil]; 
NSLog(@"%@",[[[[result objectForKey:@"sample"] objectForKey:@"nested"] objectForKey:@"tags" ] description]); 

But now I want to load this object with my mapping. My old code with loading from a server:

RKObjectManager *objectManager = [RKObjectManager sharedManager];
RKURL *URL = [RKURL URLWithBaseURL:[objectManager baseURL] resourcePath:[xmlFile path] queryParameters:nil];

[objectManager.mappingProvider setMapping:myMapping forKeyPath:myKeyPath];

[objectManager loadObjectsAtResourcePath:[NSString stringWithFormat:@"%@", [URL resourcePath]] usingBlock:^(RKObjectLoader *loader) {
    loader.delegate = self;
}];

After that I get my mapped objects in the didLoadObjects delegate of RestKit. How can I do the same for my local xml object?

I found the following solution for the problem. Works like a charm.

RKObjectMappingProvider* mappingProvider = [RKObjectManager sharedManager].mappingProvider;
RKObjectMapper* mapper = [RKObjectMapper mapperWithObject:parsedData mappingProvider:mappingProvider];
RKObjectMappingResult* result = [mapper performMapping];
if (result) {

    NSArray *resultArray = result.asCollection;

    MyMappingClass *object = [resultArray lastObject];
    NSLog(@"My Object: %@", object);
}
