我在 Ionic 中使用以下插件来可视化图像：@ionic-native/photo-viewer。

调用可视化方法时：

PhotoViewer.show('http://my_site.com/my_image.jpg', 'Optional Title', {share: true});

一切都在 Android 设备/模拟器上按预期工作。但是，当尝试在使用 iOS 设备/模拟器时调用相同的方法时，应用程序甚至在图像可视化之前就完全崩溃了。这些是应用程序崩溃时的日志：

以前有没有人遇到过这个问题，或者可能知道如何解决这个问题？我已将问题发布在插件存储库的“问题”部分，但是，由于创建者没有时间支持他的插件，我想在这里寻求帮助。有谁知道导致问题的原因以及如何解决？
