Objective-C JSON - 将 JSON 对象转换为本机对象？

{"status": "FRE", "list": [{"make": "Toyota", "id": 1, "model": "camry", "engine": "Four Cylinder"}{"make": "Ford", "id": 3, "model": "focus", "engine": "Four Cylinder"}]}

我如何提取每个“car" JSON object并将其放入本地object？我在用着SBJSON http://stig.github.com/json-framework/api/3.0/。这是我当前的代码，但当我需要能够迭代每个汽车对象并保存它时，它只能提取一个汽车元素：

NSString *responseString = [request responseString];
     NSString *responseDict = [responseString JSONValue];

     NSArray *keys = [NSArray arrayWithObjects:@"id",@"make",@"model",@"engine", nil];
     NSArray *objects = [NSArray arrayWithObjects:[responseDict valueForKeyPath:@"list.make"],[responseDict valueForKeyPath:@"list.model"],[responseDict valueForKeyPath:@"list.id"],[responseDict valueForKeyPath:@"list.engine"] , nil];

     self.car = [[NSDictionary alloc]initWithObjects:objects forKeys:keys];

使用 Jastor，而不是手动完成所有操作 -https://github.com/elado/jastor https://github.com/elado/jastor您只需要创建简单的类并initWithDictionary将为您完成整个分配工作。
