Control an app’s access to protected system services and user data.
- Bundle Resources
Before your app can access certain protected resources, like the Bluetooth interface, location information, or the user’s photos, the system asks the user for permission on behalf of your app. To signal that your app needs the access, you add a
Usage key to your app’s Information Property List. You set the value associated with the key to a string that explains why your app needs access. The system displays this string when prompting the user, as described in Requesting Access to Protected Resources.
