Use the NSString interface that comes with JSONKit. For example:
使用 JSONKit 自带的 NSString 接口。例如：
NSDictionary *deserializedData = [jsonString objectFromJSONString];
You'll either need to know in advance what sort of container you're going to get from the JSON data, or else test the object you get back to figure out its type. (You can use -isKindOfClass: for this.) Most of the time, you already have an expectation of what's in the JSON data, so you know to expect a dictionary or an array, but it's still a good idea to check the class of the object you get back.
您要么需要提前知道将从 JSON 数据中获取哪种类型的容器，要么测试返回的对象以确定其类型。（您可以为此使用 -isKindOfClass:。）大多数情况下，您已经对 JSON 数据中的内容有了预期，因此您知道需要字典或数组，但检查类仍然是一个好主意你回来的对象。
