ios10 相冊相機閃退

iOS10系統下調用系統相冊、相機功能，遇到閃退的情況，描述如下：

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

修復方法：

在info.plist文件下添加

相機權限

<key>NSCameraUsageDescription</key>

<string>cameraDesciption</string>

相冊權限

<key>NSPhotoLibraryUsageDescription</key>

<string>photoLibraryDesciption</string>
