This is actually not code, this is something you have to put on your Info.plist file.

What you are looking for is:

UIRequiresPersistentWiFi or Application uses Wifi

Here is what Apple has to say about it:

If your application accesses the network using the Wi-Fi radios, you must notify the system of that fact by including the UIRequiresPersistentWiFi key in the application’s Info.plist file. The inclusion of this key lets the system know that it should display the network selection panel if it detects any active Wi-Fi hot spots. It also lets the system know that it should not attempt to shut down the Wi-Fi hardware while your application is running.
