About the Hotspot Network Subsystem
The Hotspot Network Subsystem allows a Hotspot Helper application to participate in the process of classifying and authenticating to Wi-Fi hotspot networks. This programming guide is a companion to Apple’s NEHotspotHelper Class Reference, which describes the Hotspot Helper API.
