如何在iOS中解析从TMDB接收的此字符串
我正在iOS应用程序中从TMDB获取流行电影数据。然而，我在解析和从中获取有意义的数据时遇到了很大的困难。我对iOS完全陌生。我在Windows Phone中也做过类似的事情，我创建了Poco，并使用DataContractJsonSerializer解析数据。 但我不知道如何在iOS中做到这一点。 我想从这个字符串中检索id、原始标题和海报路径如何在iOS中解析从TMDB接收的此字符串,ios,json,themoviedb-api,Ios,Json,Themoviedb Api,我正在iOS应用程序中从TMDB获取流行电影数据。然而，我在解析和从中获取有意义的数据时遇到了很大的困难。我对iOS完全陌生。我在Windows Phone中也做过类似的事情，我创建了Poco，并使用DataContractJsonSerializer解析数据。 但我不知道如何在iOS中做到这一点。 我想从这个字符串中检索id、原始标题和海报路径 this is the data i am getting { buffer = { 0 = 123; 1 = 34;

（我想）你看过如何用Objective-C阅读JSON了吗？所以这里有很多问题。你可能也想看看像RestKit这样的东西……是的，事实上我看过。我尝试了这个和其他各种选项，我添加了我尝试过的代码。我尝试过这个，它崩溃了，所以我在数组中转换了响应。我附加了代码什么类型的对象是响应？能否显示函数调用FunctionInBackground。这是在做什么？我正在使用parse sdk及其函数，它只是从服务器获取字符串。响应是NSDictionary。那么为什么需要处理JSON？如果你已经有了NSDictionary，那就开始使用它吧？！我已经添加了我得到的确切数据，在对该数据尝试您的代码时，我得到了零值。在响应中，它说，这是一个包含7个键值对的NSDictionary。要将其转换为我的类的对象。我是否需要在我的应用程序中定义一个类似的类结构并用这些数据填充它？
