iOS AFNetworking检测网络状态

创建网络监听者管理者对象

AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];

设置监听

网络状态

//显然是枚举值

typedef NS_ENUM(NSInteger, AFNetworkReachabilityStatus) {

AFNetworkReachabilityStatusUnknown          = -1,//未识别的网络

AFNetworkReachabilityStatusNotReachable    = 0,//不可达的网络

AFNetworkReachabilityStatusReachableViaWWAN = 1,//2G,3G,4G...

AFNetworkReachabilityStatusReachableViaWiFi = 2,//wifi网络

}

-设置网络监听

[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

switch (status) {

case AFNetworkReachabilityStatusUnknown:

NSLog(@"未识别的网络");

break;

case AFNetworkReachabilityStatusNotReachable:

NSLog(@"不可达的网络(未连接)");

break;

case AFNetworkReachabilityStatusReachableViaWWAN:

NSLog(@"2G,3G,4G...的网络");

break;

case AFNetworkReachabilityStatusReachableViaWiFi:

NSLog(@"wifi的网络");

break;

default:

break;

}

}];

3.开始监听

[manager startMonitoring];
