IOS 10 Permission required for accessing Camera, Photo library …

iOS 10 Now Requires User Permission to Access Media Library, Photos, Camera and other Hardware like these. The solution for this is to add their keys into info.plist with description for user that how we are using their data , iOS already required permissions to access microphone, camera, and media library earlier (iOS6, iOS7), but since iOS10 the apps will crash if you don’t provide the description why you are asking for the permission.

There is a list of all Cocoa Keys that you can specify in your Info.plist file
