title: iOS WiFi notification API
body: <p>Is there a way to programmatically subscribe to WiFi notifications on iOS? </p>
  
  <p>For example, assuming the user has not disabled WiFi notifications, when they are within range of a WiFi network, the operating system provides a notification of available networks. Can an app subscribe to this notification and provide it's own notification to the user?</p>
  
  <p>Could the app could even check the SSID to see if it is a specific network, and then perform some action?</p>
