我正在尝试在iOS中的react-native应用程序中将截图保存到Camera Roll，但是一旦调用CameraRoll.saveToCameraRoll，应用程序就会崩溃。它一直工作到iOS 10并且反应原生0.47。它在Android中运行得非常好。
我已经拥有Info.plist中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，我没有获得上述两个控制台日志。这是一个本机崩溃，下面是崩溃线程。

我也遇到同样的问题。 通过在info.plist中添加NSPhotoLibraryAddUsageDescription（“隐私 - 照片库添加使用说明”）进行修复。
这是iOS 11的新规则。
