IOS Hardware Licensing Detection: Location services, contacts, calendars, reminders, photos, Bluetooth sharing, microphones, cameras, etc. (RPM)

Reprinted from: http://www.cocoachina.com/ios/20151214/14502.html

iOS system version of the premise of the continuous upgrade, along with the user to use the security of the device, iOS system for the app needs to use more stringent hardware restrictions, app processing a little inappropriate, the user is not aware of the function is not available, heavy will cause the app Crash.

When the user in the app launch, see the bullet out of the "XXX request access to your location" "XXX request access to your address book" "XXX request access to your Calendar" "XXX request access to your webcam" and other series of messages, users feel impatient while, will also be due to a temporary security considerations and the corresponding function to shield off, this is just the beginning, when the user really in the use of the corresponding function, there will be a continuous strange phenomenon, such as data display anomalies: There is information in the Address book, but always loading data, and some even direct crash.

Below, the author will comprehensively put the above hardware authorization detection, one by one detailed list, and give the relevant sample code:

1. Location Services
