I am currently trying to convert the JSON Representation of some Objects into an NSArray. I used RestKit to get the Response through our API and now I want to convert the RKResponse into an Array of Objects. How can I do this ?

Is there any delimeter to distinguish between your object string? Post an example response. — Ratan

 NSData* data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
    NSArray *values = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];  // if you are expecting  the JSON string to be in form of array else use NSDictionary instead

The above code works good for iOS 5 and above

What is the dataType of RKRESPONSE.Is it NSDATA or some other??

Sebastian Boldt Over a year ago

RKRESPONSE is defined inside the RestKit Headers. It has its own Type.

I can convert it to a string like the following : NSData *tempWishes = [[response bodyAsString]dataUsingEncoding:NSUTF8StringEncoding];

Works fine, and pretty simple.

Try importing RestKit/RKJSONParserJSONKit.h. Then use try the method objectFromString:error:. To get a NSDictionary representation. From the NSDictionary you can get the array.
