// 下载地址：http://pan.baidu.com/s/1gd5NNDD

// 1. 添加Reachability.h和Reachibility.m文件到项目中

// 2. 添加SystemConfiguration.framework框架

// 3. 引入Reachibility.h文件

// 4. 代码操作：

// 判断当前为那种网络

Reachability *reachability = [Reachability reachabilityWithHostName:@"www.apple.com"];

switch ([reachability currentReachabilityStatus]) {

case NotReachable:

NSLog(@"无网络连接");

break;

case ReachableViaWiFi:

NSLog(@"wifi连接");

break;

case ReachableViaWWAN:

NSLog(@"蜂窝数据");

break;

default:

break;

}
