iphone - JSonKit反序列化问题

Question

我有JSON作为NSString:

[{"bus_number":"1","created_at":"2011-08-15T23:07:52Z","id":1,"model":"Setra","registar_number":"123456","seats":50,"tour_id":1,"updated_at":"2011-08-15T23:07:52Z"},{"bus_number":"2","created_at":"2011-08-15T23:07:52Z","id":2,"model":"Mercedes","registar_number":"2234","seats":60,"tour_id":1,"updated_at":"2011-08-15T23:07:52Z"}]

并且我正在尝试将此NSString转换为NSDictionary。

当我使用时:

NSDictionary *sourceDictionary = [[response bodyAsString] objectFromJSONString];

我得到这样的NSDictionary:

(
    {
    "bus_number" = 1;
    "created_at" = "2011-08-15T23:07:52Z";
    id = 1;
    model = Setra;
    "registar_number" = 123456;
    seats = 50;
    "tour_id" = 1;
    "updated_at" = "2011-08-15T23:07:52Z";
},
    {
    "bus_number" = 2;
    "created_at" = "2011-08-15T23:07:52Z";
    id = 2;
    model = Mercedes;
    "registar_number" = 2234;
    seats = 60;
    "tour_id" = 1;
    "updated_at" = "2011-08-15T23:07:52Z";
}

)

但是，此NSDictionary存在问题，我无法访问它们的元素，某些元素不是NSStrings(例如模型)。

如何使用NSStrings将JSONString转换为NSDictionary？

编辑:

当我尝试使用以下命令登录控制台时:

for (id key in sourceDictionary) {
            NSLog(@"key: %@, value: %@", key, [sourceDictionary objectForKey:key]);
        }

我得到异常:

-[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0x1c3a50

Answer 1

这些实际上是NSString，当您将它们打印到控制台时，它们只是没有引号。
