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.
需要在应用的info.plist里加入(使用source code模式)：
<key>NSCameraUsageDescription</key> <string>cameraDesciption</string><key>NSContactsUsageDescription</key><string>contactsDesciption</string><key>NSMicrophoneUsageDescription</key><string>microphoneDesciption</string><key>NSPhotoLibraryUsageDescription</key><string>photoLibraryDesciption</string>
实际项目中，按需修改：
<key>NSCameraUsageDescription</key> <string>拉近需要访问您的相机</string>
<key>NSContactsUsageDescription</key><string>拉近需要访问您的通讯录</string>
<key>NSMicrophoneUsageDescription</key><string>拉近需要访问您的麦克风</string>
<key>NSPhotoLibraryUsageDescription</key><string>拉近需要访问您的相册</string>
