(5)如果无法区分出2G、2.5G、3G网络的区别，那么我们可以将Reachability.m中的networkStatusForFlags方法重构：
复制代码
- (NetworkStatus) networkStatusForFlags: (SCNetworkReachabilityFlags) flags
{
if ((flags & kSCNetworkReachabilityFlagsReachable) == 0)
{
return NotReachable;
}
BOOL retVal = NotReachable;
if ((flags & kSCNetworkReachabilityFlagsConnectionRequired) == 0)
{
// if target host is reachable and no connection is required
// then we'll assume (for now) that your on Wi-Fi
retVal = ReachableViaWiFi;
}
if ((((flags & kSCNetworkReachabilityFlagsConnectionOnDemand ) != 0) ||
(flags & kSCNetworkReachabilityFlagsConnectionOnTraffic) != 0))
