【Unity开发】Unity3d之MiniJson与LitJson之间的较量
来源：互联网 发布：如何处理sql注入 编辑：程序博客网 时间：2024/05/17 06:45
由于项目不得不用到json来解析服务器端传来的数据，于是不得不选择一种在unity3d上面可用的json.开始根据网上推荐LitJson,于是下载下来源码，导入项目；
经过测试可以用；但是移植到ipad时，就各种问题了，上网查问题也没结果，就发现有人说JsonMapper is not compatible with IOS，太坑爹不兼容。
于是又根据网友推荐的MiniJson,功能虽然没有litjson强大，不能够解析嵌套数组，但是可以满足自己现在的需求。最终经过两天的挣扎，测试litjson无法可用，选择了MiniJson. (测试期间还接触了jsonfx，但是导入项目时出错，就不折腾了)
