问题描述
xcode的log日志输出中文的问题,一般都是重写nsarray,nsdictionary的- (nsstring *)descriptionwithlocale:(id)locale;方法进行处理,最近升级到xcode9会后发现原来的处理逻辑也无法满足输出中文的需求,后台返回的状态描述涉及到中文的都变成了unicode编码,其实这是重写的方法失效的问题,因为xcode默认输出nsarray,nsdictionary的中文都是unicode编码
正确的解决方案如下, 创建nsarray+zylog分类
nsarray+zylog.h文件

效果
而且直接就是json串,复制log日志,直接在json格式化工具中使用
