IOS notification of wifi connection including SSID

问题

Newbie IOS programmer looking for a way to get notified when the IPhone connects to a WIFI network.

i.e. Notification for the following transitions: 3G to WIFI WIFI to 3G WIFI to another WIFI

It should be able to tell which SSID I am connected to ...

This took about 20 minutes to figure out on Android, can't find a starting point for this function on IOS

thanks

Using the code u can get the SSID data of the WIFI you are currently connected to.

CFArrayRef myArray1 = CNCopySupportedInterfaces();
CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray1, 0));
NSLog(@"%@",myDict);

For getting notification of network changes, you could drop Apple's Reachability class into your project.

As for getting SSID's, check out the solutions in the System Configuration framework's CaptiveNetwork API (documentation linked for you).
