Ios NSPhotoLibraryUsageDescription 键必须存在于 Info.plist 中才能使用相机胶卷

谢谢@rmaddy，我在Info.plist中的其他键-字符串对之后添加了这个，并解决了这个问题:

<key>NSPhotoLibraryUsageDescription</key>
<string>Photo Library Access Warning</string>

Edit:个

我的应用程序的不同组件也出现了类似的问题.到目前为止(在更新到Xcode8/iOS10之后)添加了所有这些密钥:

<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app does not require access to the microphone.</string>
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
