+(NSString *)getNetWorkStates{

int netType = 0;
//获取到网络返回码
for (id child in children) {
if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {
//获取到状态栏
netType =[[child valueForKeyPath:@"dataNetworkType"]intValue];
switch (netType) {
case 0: state = @"无网络"; break;

case 2: state = @"3G"; break;

根据状态栏获取网络状态，可以区分2G、3G、4G、WIFI，系统的方法，比较快捷。稍微蛋疼的是万一连接的WIFI没有联网的话···你懂得
