問題描述
xcode的log日志輸出中文的問題,一般都是重寫nsarray,nsdictionary的- (nsstring *)descriptionwithlocale:(id)locale;方法進行處理,最近升級到xcode9會后發現原來的處理邏輯也無法滿足輸出中文的需求,后臺返回的狀態描述涉及到中文的都變成了unicode編碼,其實這是重寫的方法失效的問題,因為xcode默認輸出nsarray,nsdictionary的中文都是unicode編碼
正確的解決方案如下, 創建nsarray+zylog分類
nsarray+zylog.h文件

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