AFNetworking reachabilityForLocalWiFi

Question

是否有一种与AFNetworking 2等价的方法

[Reachability reachabilityForLocalWiFi];

Answer 1

我查看了Apple的可达代码，我认为这将完成任务。

- (AFNetworkReachabilityManager*) reachabilityForLocalWifi
{
    struct sockaddr_in localWifiAddress;
    bzero(&localWifiAddress, sizeof(localWifiAddress));
    localWifiAddress.sin_len = sizeof(localWifiAddress);
    localWifiAddress.sin_family = AF_INET;

    // IN_LINKLOCALNETNUM is defined in <netinet/in.h> as 169.254.0.0.
    localWifiAddress.sin_addr.s_addr = htonl(IN_LINKLOCALNETNUM);

    return [AFNetworkReachabilityManager managerForAddress:&localWifiAddress];
}

Answer 2

NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];

NSOperationQueue *operationQueue = manager.operationQueue;
[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
    case AFNetworkReachabilityStatusReachableViaWWAN:
    case AFNetworkReachabilityStatusReachableViaWiFi:
        [operationQueue setSuspended:NO];
        break;
    case AFNetworkReachabilityStatusNotReachable:
    default:
        [operationQueue setSuspended:YES];
        break;
}
}];

我正在使用这个在我的自定义客户端的一些项目，以检查互联网的可达性。参考afnetworking链路
