【问题描述】：

我正在尝试从 twitter 帐户获取关注者列表。 我需要从这些朋友那里得到一份名单。

我正在尝试使用以下代码获取具有这些名称的数组：

NSArray *users = [twitterFriends objectForKey:@"name"];

但它崩溃了..

这是我的 json 响应。

【问题讨论】：

@"name" 键的对象是字符串，而不是数组。

你如何获得关注者的名字，我想要这个名字你能告诉我你的代码吗...

【参考方案1】：

假设twitterFriends是字典的根数组，你可以通过这样做得到名字列表：

NSArray *names = [twitterFriends valueForKeyPath:@"name"];
