iOS: Check for Internet Connection?

[Rick Harrison]

Hi there,

Is there a way to invisibly check if an
iPhone has an active internet connection?

I’d rather do that if possible than have
to ask the user if he/she is presently
connected to the internet.  I thought
I would toggle some of the capabilities
of my iOS app on or off depending on
whether or not an internet connection
is currently available.

Suggestions?  Ideas?

Thanks,

Rick
