ios 使用友盟統計的錯誤分析時有些東西是沒法定位到哪一個方法或類出錯了，只返回簡單的內存地址。例如上面的錯誤代碼ios

這時候咱們須要本身去查找錯誤的方法或類，以便修復bug；大概操做步驟以下：app

一、在Archives 中選中一個，show in finder －－>顯示包內容－－>在dSYMs 中有 xxxxxx.app.dSYM ，在Products/Applications 有xxxxxx.app 把這2個文件放在同一個文件夾裏面。ide

二、打開終端 cd 到這個文件目錄下oop

三、輸入指令 spa

xcrun atos -arch armv7s -o xxxxxx.app/xxxxxx 0xaf8a5 code

注：armv7s 是友盟錯誤裏面的內存
