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.
意思就是说，你需要在 info.plist 文件添加一个 NSPhotoLibraryUsageDescription
的 key，然后添加一个描述。
在项目中找到info.plist
文件，右键点击以 Source Code 形式打开
<key>NSCameraUsageDescription</key> <string>cameraDesciption</string>
<key>NSContactsUsageDescription</key> <string>contactsDesciption</string> <key>NSMicrophoneUsageDescription</key> <string>microphoneDesciption</string>
