NEHotspotHelper background

In general, terminating an app from the multitasking UI is considered by the system as a hint from the user that they don’t want the app to ever launch in the background again (this flag gets cleared when the user next manually launches the app). I’m not sure if this applies to hotspot helper code, but it seems likely.

If you want to test your app’s behaviour in the ‘launch in the background’ case, it’s best not to terminate the app that way. Rather, add a (debug only) button to your UI that calls

exit

Thanks for your reply eskimo.

Turns out it does seem to fully work in the background (after being force closed) afterall.

I had address sanitizer turned on, which was immediately crashing my app when not launched by the debugger (ie when iOS was trying to wake the app up to authenticate with the wifi).

For me it only calls kNEHotspotHelperCommandTypeEvaluate and kNEHotspotHelperCommandTypeFilterScanList all the time in background. My wifi network has both password protection and captive network also but I never get cmd.commandType == kNEHotspotHelperCommandTypeAuthenticate or kNEHotspotHelperCommandTypePresentUI called.

Is there any specific reason or way to call it?

For it to send you

.Authenticate

.Evaluate

Dear Eskimo ,

I do have same issue I could receive kNEHotspotHelperCommandTypeEvaluate and kNEHotspotHelperCommandTypeFilterScanList in my code . But kNEHotspotHelperCommandTypeAuthenticate command never gets called . I am trying to connect captive newtwok ( i.e. public WiFi Hotspot) . The html login page is not coming at all .

How i can connect captive newtwok ( i.e. public WiFi Hotspot) programatically using NEHotspotHelper ? . Please provide sample code to be written for kNEHotspotHelperCommandTypeEvaluate command .

I responded on the other thread.

I was also having an issue receiving kNEHotspotHelperCommandTypeAuthenticate. When my helper is in the Evaulating state, I check my connected network via [NEHotspotHelper supportedNetworkInterfaces] then compare that network to my list of networks that have a level of confidence. Once I deliever the response, the handler receives the Authenticate command. My code:

if (cmd.commandType == kNEHotspotHelperCommandTypeEvaluate) {
/ *   When a network is joined initially, the state machine enters
  
  *   the Evaluating state. In that state, each HotspotHelper receives a
  
  *   command of type Evaluate. If one or more helpers indicates that it
  
  *   is able to handle the network, the one with the highest confidence
  
  *   level is chosen before entering the Authenticating state. As an
  
  *   optimization, the first helper to assert a high confidence wins and
  
  *   the state machine ignores the other helpers.
  
  *
  
  *   If no helpers claim the network, the state machine enters the
  
  *   Authenticated state.
