I’m developing two separated applications but there is a plist file for one of those app contains data that I need it on the other one.
is there is any way to get data? in case yes please show me some sample code? what about the NSUserDefault could it be useful?
NSUserDefault will not work. You need to create a custom URL scheme for your app and then you will be able to pass some data to your another app.
follow these url’s you will find what you want.
