Answer 1

You can not modify files with the application bundle..

Answer 2

Because the settings bundle resides inside your app's bundle, you cannot change it at runtime, only at compile-time.

You can, however, use NSUserDefaults to set the value at runtime, and the settings application will automatically reflect this. It will be saved elsewhere, though. You can just read it back the same way as you would do with the settings bundle, also through NSUserDefaults.

Note that you shouldn't read from the settings bundle directly, as it makes no sense. You should always fetch and set user defaults using NSUserDefaults. When the user makes a change in the settings application, NSUserDefaults will reflect this automatically. They will always be kept in sync.
