iOS-Reachability的使用

// 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;

}

 

#pragma mark 判断时候为wifi

- (BOOL)isEnableWIFI

{

    return ([[Reachability reachabilityForLocalWiFi] currentReachabilityStatus] != NotReachable);

}

#pragma mark 判断时候为3G

- (BOOL)isEnable3G

{

    return ([[Reachability reachabilityForInternetConnection] currentReachabilityStatus] !=NotReachable);

}

#pragma mark 判断是否有网络连接

- (BOOL)isNetwork

{

    if (([[Reachability reachabilityForLocalWiFi] currentReachabilityStatus] == NotReachable) &&

        ([[Reachability reachabilityForInternetConnection] currentReachabilityStatus] == NotReachable)) {

        return NO;

    }

    return YES;
