IOS-利用AFNetworking监听网络状态

来源：互联网发布：c语言编程序循环语句编辑：程序博客网时间：2024/04/29 23:24

步骤

1.创建网络监听者管理者对象

AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];

2.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];

代码

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{    //创建网络监听管理者对象    AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];    /*     typedef NS_ENUM(NSInteger, AFNetworkReachabilityStatus) {     AFNetworkReachabilityStatusUnknown          = -1,//未识别的网络     AFNetworkReachabilityStatusNotReachable     = 0,//不可达的网络(未连接)     AFNetworkReachabilityStatusReachableViaWWAN = 1,//2G,3G,4G...     AFNetworkReachabilityStatusReachableViaWiFi = 2,//wifi网络     };     */     //设置监听    [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;        }    }];    //开始监听    [manager startMonitoring];}
