ios - iOS 中 CameraRoll.saveToCameraRoll 上的应用程序崩溃

Question

我正在尝试在我的 iOS react native 应用程序中将屏幕截图保存到相机胶卷，但一旦调用 CameraRoll.saveToCameraRoll，应用程序就会崩溃。它一直工作到 iOS 10 和 react-native 0.47。它在 Android 中运行良好。

我已经在 Info.plist 中拥有 iOS 10+ 所需的权限。

这是我将图像保存到相机胶卷的代码。

CameraRoll.saveToCameraRoll(mUri, 'photo')
.then(()=>console.log('saved to CameraRoll'))
.catch(()=>console.log('error in saving'))

请注意，我没有收到以上两个的任何控制台日志。这是 native 崩溃，下面是崩溃线程。

我也遇到了同样的问题。通过在 info.plist 中添加 NSPhotoLibraryAddUsageDescription("Privacy - Photo Library Additions Usage Description") 修复。

这是 iOS 11 的新规则。
