如何将 @State 值分配给另一个 viewModel 发布的属性

如何将一个视图中的 @State 值 secondaryMarked 分配给 @Published SampleViewModel 属性？喜欢 SampleViewModel.secondMarked

这是示例：

 struct ContentView: View {
    @EnvironmentObject var sampleViewModel: sampleViewModel
            @State var firstMarked = false
            @State var secondMarked = true 
            @State var thirdMarked = false
    
    var body: some View {
        VStack {
            CheckboxField(id: "Completed", label: "Completed", isMarked: $firstMarked)
            CheckboxField(id: "Completed", label: "Completed", isMarked: $secondMarked)
            CheckboxField(id: "Completed", label: "Completed", isMarked: $thirdMarked)
        }
        .padding()
    }
}

而不是有@State and a @Published属性为它，只需使用一个。

例如，你的：

CheckboxField(id: "Completed", label: "Completed", isMarked: $firstMarked)

尝试这个：

CheckboxField(id: "Completed", label: "Completed", isMarked: $sampleViewModel.firstMarked)
