Suppose I have a application which fetch data from network and then showing those data in application. But sometimes internet becomes disconnected so I am showing message that ‘Internet not available’. But I want to keep user busy with the application. So I want to do following things but there are some problem in implementation.

1) When network disconnected I want to show message ‘network disconnect’ and I want to store all data in db.
Problem: How will I know network is not available without happening any event?

2) And when network is connected I want to fetch data and store in buffer.
Problem : Same, how will I know network is available rightnow?

    This is quite common question and is best solved using Reachability class.

    You can find a nice manual here: Testing Network Reachability

    And a quick answer is the accepted answer here:

    iPhone reachability checking

    But be aware that it’s best to check for host availabiility. I tested this code when device was connected to AdHoc WiFi (with no internet connectivity) and the result was: internet available via WiFi. So if you want to be sure – use host status.

    EDIT: and this is probably the best example on SO (answer from iWasRobbed):

    How to check for an active Internet connection on iOS or OSX?
