 8     // 获得Reachability对象
 9     self.reachability = [Reachability reachabilityForInternetConnection];
10     // 开始监控网络
11     [self.reachability startNotifier];

13 //    // 1.获得Reachability对象
14 //    Reachability *wifi = [Reachability reachabilityForLocalWiFi];
15 //    
16 //    // 2.获得Reachability对象的当前网络状态
17 //    NetworkStatus wifiStatus = wifi.currentReachabilityStatus;
