NEHotspotHelper试图在iOS上对网络进行身份验证

Question

我已经注册了使用Network Extension API的应用程序，并在注释here之后启用了后台模式。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不能在所需的wifis上设置我的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是匹配的，因此代码在所需的wifi上执行，Try here应该出现在wifi设置的MySSID下，并且密码也应该被应用，但是这两件事都不起作用。

知道密码出了什么问题吗？谢谢

我找到了解决办法。我所做的不是在找到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:设置数组中的所有网络：

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“在这里尝试”，并且我可以加入网络，而不需要手动添加密码。
