Understanding iBeacon permissions

It's important to understand that apps using the Core Location framework are essentially monitoring location, and therefore, they have to ask the user for their permission. The authorization status of a given application is managed by the system and determined by several factors. Applications must be explicitly authorized to use location services by the user, and the current location services must themselves be enabled for the system. A request for user authorization is displayed automatically when your application first attempts to use location services.

Requesting the location can be a fine balancing act. Asking for permission at a point in an app, when your user wouldn't think it was relevant, makes it more likely that they will decline it. It makes more sense to tell the users why you're requesting their location and why it benefits them before requesting it so as not to scare away your more squeamish users.
