ip address change notifications
问题 I'm using the Reachability class to detect wifi availability. There are some situations when an ipad will be connected to one wifi network,and a user will connect to another available wifi network. During these network transitions reachable->unreachable->reachable notifications are not generated. This connection change where the ip address of the ipad changes is what Im trying to listen for. Do notifications for local wifi connection changes exist or will I have to just poll my ip
