REST APIのObjective-CでJSONを解析する

Question

NSJSONSerializationを使用して、このサンプルJSONをREST APIから解析する際に問題が発生しています。

私はオプションNSJSONReadingallowfragmentを使用していますが、JSONに変換されていません。それはまだNSStringです。

NSError *jsonError = nil; 
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData: responseData options: NSJSONReadingMutableContainers error: &jsonError]; 

if (!jsonArray) { 
    NSLog(@"Error parsing JSON: %@", e); 
} else { 
    for(NSDictionary *item in jsonArray) { 
     NSLog(@"Item: %@", item); 
    } 
}
