i want to populate few fields in third party iphone apps with the desired values. is there any way i can achieve this. Can a CORE DATA file be used for this.

Each app is run in its own private environment, so no two apps can interact with each other. This is by design and necessary for security/consistency/etc reasons.

Check out these Apple RuntimeEnvironment Docs.

Maybe, but only if the 3rd party app has been run before yours on the same device, and has registered a custom URL handler for the purpose of populating fields. Or perhaps if the app downloads these fields over the network from a server with a public API for configuring the fields.

Not otherwise, as the iOS security sandbox will prohibit this communication between apps.
