一些pod问题

library not found -AFNetworking:

这个问题比较难搞，建议以下方法挨个试，祝大家好运～～

先去设定build settings里面的other link flag，将里面的内容都删除掉，然后只留下“$(inherited)”。就可以了，再去命令运行pod update

-若出现`ld: library not found for -lPods-AFNetworking`类似的， 设置`Project`->`Pods`的`Build Active Architecture Only`为`NO`

+若出现`ld: library not found for -lPods-AFNetworking`类似的， 设置`Project`->`Pods`下所有第三方库的`Build Active Architecture Only`为`NO`
