YYKit判断当前网络情况和AFN监听当前网络情况

 YYReachability * reach = [[YYReachability alloc] init];
    
    
    NSString *net = @"WIFI";
    
    switch (reach.status) {
            
        case YYReachabilityStatusNone:
            
            net = @"NONET";
            
            break;
            
        case YYReachabilityStatusWWAN:
            
            net = @"蜂窝数据";
            
            
            break;
            
        case YYReachabilityStatusWiFi:
            
            net = @"WIFI";
            
        default:
            
            break;
            
    }

AFN
