I am using the UIApplicationDidBecomeActiveNotification to refresh my tableview when the app becomes active. My problem is that in my ViewWillAppear, I am also calling a method to refresh this table’s data.
This is causing the table to be refreshed twice upon application launch. How can I get one of them not to fire when the app is initially launched? Refreshing the table has some intensive processing of network and local data.. so I would really like o only perform this action once.
Thanks.
One way to do it would be with a flag, that you can set up in
didFinishLaunching, since that is only executed once per launch.
