日常消滅警告，遇到問(wèn)題如下
ld: warning: object file (/Users/wanglizhi/wanglizhi/workspace/特運(yùn)通/特運(yùn)通/特運(yùn)通/gaode/MAMapKit.framework/MAMapKit(MAMapKit-arm64-master.o)) was built for newer iOS version (11.1) than being linked (7.0)

This was likely caused by different translation units being compiled with different visibility settings.
這個(gè)問(wèn)題產(chǎn)生的原因是MAMapKit-arm64-master.o支持的最低版本是11.1，而我項(xiàng)目支持的最低版本是8.0
解決辦法有兩個(gè)：
一、將項(xiàng)目支持的最低版本改為11.1
顯然不現(xiàn)實(shí)。
二、在Build Settings -> other lingker Flags 中添加-w 。
以下是我的項(xiàng)目解決前后的警告數(shù)量。

說(shuō)到解決這個(gè)問(wèn)題就要說(shuō)一下天朝最牛b的搜索引擎百度，我一個(gè)月之前就在解決這個(gè)問(wèn)題，一直百度不到方案，后來(lái)新需求比較急就忽略了，今天想起來(lái)之后就google了一下，瞬間解決。

搜索結(jié)果如下：看google一屏幕都是解決方案，我是不知道百度都在干些什么，光顧著打廣告掙錢(qián)了？
