iphone SDK detect Wifi and Carrier network

Question

my app accesses the internet and i just want to detect whether there is a connection either via wifi or via carrier data network or not

apple has made an example for that "Reachability"

https://developer.apple.com/iphone/library/samplecode/Reachability/

i think it just detects the wifi and not the carrier network

can anyone tell me, whats the best to be done to detect if there's a connection ( any type of connection )

Appreciate ur help!

Answer 1

That sample is exactly what you need.

Look at Reachability.m. it'll tell you whether you have any connection, and then tell you what kind of connection you have.

Answer 2

The Reachability example may be overkill if you just want to detect whether or not you are connected, and what type of connection you are using if you are connected. Indeed the example also contains code showing how to setup and use callbacks that notify you of state changes.

For a snippet of source code telling you exactly if you are connected or not, and what type of connection you are using, you may want to take a look at my answer to a similar question, posted here.
