In iOS, how do I parse a JSON string into an object

Question

I come from Android dev, so sorry if I\'m missing obvious iOS concepts here.

I have a JSON feed that looks like:

{\"directory\":[{\"id\":0,\"fName\":\"...\

you can use NSJSonSerialisation or AFNetworking library. Here is the example of AFNetworking to parse json response

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
    NSDictionary *json = (NSDictionary *)responseObject;
    NSArray *staffArray = json[@"directory"];

[staffArray enumerateObjectsUsingBlock:^(id obj, NSUInteger index, BOOL *stop){
      Staff *staff = [[Staff alloc] init];
    staff.id = [[obj objectForKey:@"id"] integerValue];
    staff.fname = [obj objectForKey:@"fName"];
    staff.lname = [obj objectForKey:@"lName"]; 

   //add data to new array to store details
   [detailsArray addObect:staff);
} ];

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}]; 

then use Core Data framework to store data.
