1.算法描述 Reachability在 Wikipedia中的定义是这样的: In graph theory, reachability refers to the ability to get from one vertex to another within a graph. We say that a vertex s can reach a vertex t (or that
相信大家在判断网络状况的时候,都会用到 Reachability 。 但是在iOS5发布以后,将其导入项目中就会出现下面一个警告 Declaration of 'struct sockaddr_in' will not be visible outside of this function 解决方法很简单,只要在其头文件中添加 #import <netinet/in.h> 警告就解
