感谢@rmaddy，我在 Info.plist 中的其他键字符串对之后添加了这个并修复了问题：

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

编辑：

我最终在我的应用程序的不同组件上也遇到了类似的问题。到目前为止添加了所有这些键（更新到 Xcode8/iOS10 之后）：

<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>
