NSArray *arr = [[operation.result objectForKey:@"data"] valueForKey:@"name"];
NSArray *arrId = [[operation.result objectForKey:@"data"] valueForKey:@"id"];
NSArray *folder=[[operation.result objectForKey:@"data"]valueForKey:@"type"];
[dictDocument setObject:arrId forKey:@"ID"];
[dictDocument setObject:arr forKey:@"Name"];
[dictDocument setObject:folder forKey:@"type"];
Arrid===>folder.id,file.id
arr===>文件名
文件夹====>文件类型例如文件夹,音频,视频我无法访问嵌套文件夹的文件??
