将我的数组内容排序到网格中 [SwiftUI]

Question

我需要将我的 Array 的内容显示到一个网格中（因此混合了 HStack 和 VStack）。我找到了这个资源：https://www.hackingwithswift.com/quick-start/swiftui/how-to-position-views-in-a-grid

如果您需要显示静态内容（在示例中为文本和图像），这将直接工作。

但是现在，我需要能够进行相同的显示，但使用数组的内容（没有大小限制，数组可以有 3 或 10 个项目）

所以需要转换我的实际代码：

ForEach(myarray.indices, id: \.self) { index in
    myView(Value: myitem[index].value, Type: myitem[index].type)
}

这样它就可以被包装成一个网格列表。

这一定很简单，但我是 SwiftUI 新手，我不知道该怎么做，我尝试调整链接中的代码但没有机会...

有什么想法吗？ 谢谢！

Answer 2

struct ContentView: View {

    let myArray = [
        [1, 2, 3],
        [4, 5, 6],
        [7, 8, 9]
    ]

    var body: some View {

        VStack {
            ForEach(myArray, id: \.self) { row in
                HStack {
                    ForEach(row, id: \.self) { number in
                        Text(String(number))
                    }
                }
            }
        }
    }
}

这是一个排列成简单网格的数组。
