日常消滅警告，遇到問題如下
ld: warning: object file (/Users/wanglizhi/wanglizhi/workspace/特運通/特運通/特運通/gaode/MAMapKit.framework/MAMapKit(MAMapKit-arm64-master.o)) was built for newer iOS version (11.1) than being linked (7.0)
ld: warning: direct access in function 'sgi::hashtable<sgi::pair<int const, signed char>, int, sgi::hash<int>, sgi::_Select1st<sgi::pair<int const, signed char

This was likely caused by different translation units being compiled with different visibility settings.

這個問題產生的原因是MAMapKit-arm64-master.o支援的最低版本是11.1，而我專案支援的最低版本是8.0
解決辦法有兩個：
一、將專案支援的最低版本改為11.1
顯然不現實。
二、在Build Settings -> other lingker Flags 中新增-w 。
以下是我的專案解決前後的警告數量。
