小编ALe*_*opa的帖子

所以我一直在干预将一个小型 SwiftUI iPad 应用程序“移动”到 Mac，并且我在使用UIDocumentPickerViewController. 我已经包裹UIDocumentPickerViewController在一个UIViewControllerRepresentable像这样：

struct DocumentPickerView: UIViewControllerRepresentable {
  func makeUIViewController(context: Context) -> UIDocumentPickerViewController {
    let documentPicker = UIDocumentPickerViewController(documentTypes: [(kUTTypeImage as String)], in: .import)
    return documentPicker
  }

  func updateUIViewController(_ uiViewController: UIDocumentPickerViewController, context: Context) {

  }
}

并像这样显示它：

struct ContentView: View {
@State var shows = false
var body: some View {
    Button(action: { self.shows.toggle() }) {
        Text("Select File")
    }
    .sheet(isPresented: self.$shows) {
        DocumentPickerView()
    }
  }
}

在 iPad 上一切正常，

但是当在 Mac 上时，UIDocumentPickerViewController …

我今天要面对的是滚动查看器，事实上它会阻止我的事件。SO..这里有一些 xaml：

    <ScrollViewer x:Name="scrollv" Panel.ZIndex="15" Margin="8,65.5,0,22" VerticalScrollBarVisibility="Visible" Height="392.5" Background="White" IsHitTestVisible="False">
        <Grid x:Name="listaintrebari" Height="Auto" Width="301.5" HorizontalAlignment="Left" VerticalAlignment="Top" Background="White" >

        </Grid>

    </ScrollViewer>

所以事情是：在滚动查看器内部的网格上，我以编程方式添加问题 UserControl...其中顺便有一个带有单击事件的按钮。我的问题是我无法单击该按钮...就像滚动查看器一样就像一个隐形的盾牌一样，保护用户控件和按钮免受邪恶鼠标的侵害！

任何帮助表示赞赏！
