RestKit：如何映射任意字符串

Question

有很多關於如何將RestKit與集成網絡堆棧一起使用的示例，但是，我只想採用JSON字符串並將其映射到對象。

如何使用RestKit，當前版本（0.20.x）執行此操作？

我沒有找到文檔中的答案：

NSString* JSONString = @"{ \"name\": \"The name\", \"number\": 12345}"; 
NSString* MIMEType = @"application/json"; 
NSError* error; 
NSData *data = [JSONString dataUsingEncoding:NSUTF8StringEncoding]; 
id parsedData = [RKMIMETypeSerialization objectFromData:data MIMEType:MIMEType error:&error]; 
if (parsedData == nil && error) { 
    // Parser error... 
} 

NSDictionary *mappingsDictionary = @{ @"someKeyPath": someMapping }; 
RKMapperOperation *mapper = [[RKMapperOperation alloc] initWithRepresentation:parsedData mappingsDictionary:mappingsDictionary]; 
NSError *mappingError = nil; 
BOOL isMapped = [mapper execute:&mappingError]; 
if (isMapped && !mappingError) { 
    // Yay! Mapping finished successfully 
}
