ios - 执行 UI 块时引发 React Native 异常：一个视图一次只能与一个视图控制器关联

Question

我有这个问题。我似乎找不到解决方案。我正在尝试实现一个对话框。它在 Android 上运行良好。但目前在 iOS 上遇到了麻烦。请帮忙 ：（

    Exception thrown while executing UI block: A view can only be associated with at most one view controller at a time! View <RCTView: 0x7fe0e7e62ad0; reactTag: 355; frame = (0 0; 414 896); layer = <CALayer: 0x600003a877c0>> is associated with <UIViewController: 0x7fe0e7c4e450>. Clear this association before associating this view with <UIViewController: 0x7fe0e7c56060>.
