这篇文章主要介绍了iOS中Xcode9的Log日志无法输出中文怎么办,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
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
