When core data is changed, how to update the table view data?
Using NSXMLParser to get data from an xml file on internet with an update button to get update database and store it by using xcode template core data.
However, when I updated all core data, console can only show right data until I quited the app and run it  again. 
Any way to update all data correctly without quiting the app?
