error: writeToFile写入不成功/无法写入的原因

[cacheDic writeToFile:cacheURL atomically:YES];

后却返回no，查阅手册发现：

If an array or dictionary contains objects that are not property-list objects, then you cannot save and restore the hierarchy of data using the various property-list methods and functions.

分析:

1. 也就说要存的不能为你自定义的对象，也不能是null
2. 服务器返回数据中含有数个null

fix - BUG: OC暂时无法解决,在线解析数据
