 Starting with iOS 8, you **must** provide a description for how your app uses location services by setting a string for the key [`NSLocationWhenInUseUsageDescription`](https://developer.apple.com/library/ios/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW26) or [`NSLocationAlwaysUsageDescription`](https://developer.apple.com/library/ios/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW18) in your app's `Info.plist` file. INTULocationManager determines which level of permissions to request based on which description key is present. You should only request the minimum permission level that your app requires, therefore it is recommended that you use the "When In Use" level unless you require more access. If you provide values for both description keys, the more permissive "Always" level is requested.
