Apple has created that famous Reachability class but looking at the code I don't trust it much. The formatting and header is messy.
Also it provides no help for showing that "You have no internet!" alert.
I just want to do:
At some point download a XML.
When there is no internet, show alert.
When internet disconnects while downloading the XML, show alert.
In my app the user taps no download button it all happens automatically in the background.
That's it. Really. I spent now 3 hours with Reachability my brain just rejects it.
Did someone create a clever alternative with a clean header and clean code? Something that is really simple to use?
I've found one on GitHub: https://github.com/tonymillion/Reachability
Note: First find != necessarily best find.
Maybe its too late to respond, but following answer can help someone looking for solution to same problem, as I answered here.
