这是我的Json文件 “结果”：
      {
         “ID”：197753，          “名字”：“胡凯莉”，          “wikipedia_id”：20646206，          “游离碱”： “/米/ 03l7xc”，          “IMDB”： “nm0005026”          “themoviedb”：11024，          “tvrage”：497，          “社会”：{
            “推特”：{
               “twitter_id”：51649635，                “链接”： “https://twitter.com/KellyHu”             }          }，          “图像”：{

Answer 1

{
"id":753924,
"name":"Kelly Byrns",
"images":[]
}

响应json不正确。当没有图像时，它返回一个空数组，不是字典。

因此，您可以检查obj[@"images"]类型，或要求服务器始终返回字典。
