Ios [[BoxSDK sharedSDK].foldersManager createFolderWithRequestBuilder:builder成功：成功：失败]未工作

我在box.com中创建文件夹时遇到问题。这是我的代码。我在foldersManager createFolderWithRequestBuilder中遇到问题，如果我在返回的断点上得到“op=POST”

什么是self.folderID？ 它应该是框中存在的文件夹的有效文件夹ID。 要保存到“所有文件”，请从builder.parentID=@“0”开始

顺便说一句，您在故障块中得到的错误消息是什么？ 是否执行故障块？ 我说的是这句话：

---

NSLog（@“文件夹创建失败，错误代码：%i”，响应。状态代码）

我改为builder.parentIDD=@“0”；得到了同样的结果。成功和失败都会阻碍执行。
