升级iOS10后访问相机、相册、麦克风、通信录闪退

升级了iOS10和xcode8，发现访问相机、相册、麦克风、蓝牙、日历等时会出现闪退，控制台给出这样的信息：

This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

根据提示须要在plist中加入NSCameraUsageDescription
一般须要添加以下权限说明（相机、通信录、麦克风、相册）：

Key:NSCameraUsageDescription    Type:String Value:cameraDesciption
Key:NSContactsUsageDescription    Type:String  Value:contactsDesciption
Key:NSMicrophoneUsageDescription  Type:String  Value:microphoneDesciption
Key:NSPhotoLibraryUsageDescription Type:String  Value:photoLibraryDesciption
