ios - NEHotspotHelper 问题尝试在 iOS 上验证网络

Question

我已经为使用 Network Extension API 注册了我的应用程序，并根据评论 here 启用了后台模式.因此，当用户进入 wifi 设置时，我能够看到范围内的 wifis 列表，但我不知道为什么我无法在所需的 wifis 上设置自定义语句并设置密码。

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:@"Try here", kNEHotspotHelperOptionDisplayName, nil];

dispatch_queue_t queue = dispatch_queue_create("com.myapp.ex", 0);  // dispatch_get_main_queue()

BOOL isAvailable = [NEHotspotHelper registerWithOptions:options queue:queue handler: ^(NEHotspotHelperCommand * cmd) {

    if(cmd.commandType == kNEHotspotHelperCommandTypeEvaluate || cmd.commandType == kNEHotspotHelperCommandTypeFilterScanList) {

        for (NEHotspotNetwork* network  in cmd.networkList) {

            if ([network.SSID isEqualToString:@"MySSID"]) {

                [network setConfidence:kNEHotspotHelperConfidenceHigh];
                [network setPassword:@"mypassword"];

                // This is required
                NEHotspotHelperResponse *response = [cmd createResponse:kNEHotspotHelperResultSuccess];
                [response setNetwork:network];
                [response deliver];

                NSLog(@"Confidence set to high for ssid: %@ (%@)\n\n", network.SSID, network.BSSID);
            }  
        }    
    }
}];

SSID 匹配，所以代码在所需的 wifi 上执行，Try here 应该出现在 wifi 设置的 MySSID 下，密码也应该应用, 但两者都不起作用。

知道代码有什么问题吗？谢谢

我找到了一个解决方案。我没有在找到 ssid 时创建响应，而是创建一个数组并添加与我的 ssid 匹配的网络，然后调用 createResponse: 在我的数组中设置所有网络:

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:@"Try here", kNEHotspotHelperOptionDisplayName, nil];

dispatch_queue_t queue = dispatch_queue_create("com.myapp.ex", 0);

BOOL isAvailable = [NEHotspotHelper registerWithOptions:options queue:queue handler: ^(NEHotspotHelperCommand * cmd) {

    NSMutableArray *hotspotList = [NSMutableArray new];

    if(cmd.commandType == kNEHotspotHelperCommandTypeEvaluate || cmd.commandType == kNEHotspotHelperCommandTypeFilterScanList) {

        for (NEHotspotNetwork* network  in cmd.networkList) {

            if ([network.SSID isEqualToString:@"MySSID"]) {

                [network setConfidence:kNEHotspotHelperConfidenceHigh];
                [network setPassword:@"mypassword"];

                NSLog(@"Confidence set to high for ssid: %@ (%@)\n\n", network.SSID, network.BSSID);

                [hotspotList addObject:network];
            }  
        }

        NEHotspotHelperResponse *response = [cmd createResponse:kNEHotspotHelperResultSuccess];
        [response setNetworkList:hotspotList];
        [response deliver];
    }
}];

现在我可以在 SSID 名称下看到“Try here”，无需手动添加密码即可加入网络。
