Connectivity

Connectivity is a wrapper for Apple’s Reachability providing a reliable measure of whether Internet connectivity is available where Reachability alone can only indicate whether an interface is available that might allow a connection.

Connectivity’s objective is to solve the captive portal problem whereby an iOS device is connected to a WiFi network lacking Internet connectivity. Such situations are commonplace and may occur for example when connecting to a public WiFi network which requires the user to register before use. Connectivity can detect such situations enabling you to react accordingly.

Features:

•  Detect captive portals when a device joins a network.
•  Detect when connected to a router that has no Internet access.
•  Be notified of changes in Internet connectivity.
•  Polling connectivity checks may be performed where a constant network connection is required (optional).
