When we update an application, the settings which are selected by the user in the old version should be kept after updating to the newer version.

Let me explain this with an simple example:

Version 1.0 of my app has a switch that is ON by default but the user can set OFF. In the App Store I am going to publish next version— 1.1—with some modification but it also has the same switch. When the user updates it from the device the switch value should stay OFF.

How can I achieve this kindly reply me with your valuable comments…

Thanx in advance…

    App 1.1 can easily read what App 1.0 wrote.
