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

升级xcode 8 以后在iOS 10运行程序出奔溃

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

描述的意思是需要在 info.plist 文件添加一个NSPhotoLibraryUsageDescription的 key，然后添加一个描述。

找到项目中info.plist文件，在其中添加

<key>NSBluetoothPeripheralUsageDescription</key>

<string>蓝牙权限</string>

<key>NSCameraUsageDescription</key>

<string>使用相机权限</string>

<key>NSMicrophoneUsageDescription</key>

<string>使用麦克风权限</string>

<key>NSPhotoLibraryUsageDescription</key>

<string>使用相册权限</string>

以上<key>注意不能写错，而<string>则为描述

这是利用Source Code形式打开的info.plist 文件，也可以使用info.plist 文件中的“＋”进行添加key值。
