可滚动的全屏视图 swift

Question

我希望在 Swift UI 中创建全屏可滚动视图。将视图放入滚动视图和垂直堆栈后，我无法让视图全屏显示？有什么建议么？

这是我的代码的样子

struct ContentView : View {
    var body: some View {

        //var posts = [Post(postColor: .red), Post(postColor: .blue), Post(postColor: .green)]
        ScrollView(.vertical, showsIndicators: false) {

            VStack {
                Post(postColor: .red)
                Post(postColor: .blue)
                Post(postColor: .green)

            }
        }
    }

}

struct Post : View {

    var postColor : Color

    var body : some View {

        VStack(alignment: .leading) {

                HStack {
                    Text("Name")
                        .font(.title)
                        .fontWeight(.heavy)

                    Spacer()
                   }

                Text("@Username")
                    .lineLimit(nil)
                    .font(.body)


                   Spacer()
                   }.background(postColor)

    }

}

您可以使用 GeometryReader 来实现：

struct FullScreenViewsInScrollView: View {
    var body: some View {

        GeometryReader { geometry in

            ScrollView {

                VStack(spacing: 0) {
                    Rectangle()
                        .foregroundColor(.red)
                        .frame(height: geometry.size.height)

                    Rectangle()
                        .foregroundColor(.blue)
                        .frame(height: geometry.size.height)

                    Rectangle()
                        .foregroundColor(.green)
                        .frame(height: geometry.size.height)
                }

            }

        }
    }

}

结果应该是（我在实时预览中向下滚动了一点）：
