SwiftUI HStack 以等间距填充整个宽度

发布于02月10日

我有一个HStack:

struct BottomList: View {
    var body: some View {
        HStack() {
            ForEach(navData) { item in
                NavItem(image: item.icon, title: item.title)
            }
        }
    }
}

How do I perfectly center its content with equal spacing automatically filling the whole width?

仅供参考，就像 bootstrap CSS class .justify-content-around一样

推荐答案

frame布局修改器(maxWidth参数为.infinity)可以用来实现这一点，而不需要额外的Shape视图.

struct ContentView: View {
    var data = ["View", "V", "View Long"]

    var body: some View {
    VStack {

        // This will be as small as possible to fit the data
        HStack {
            ForEach(data, id: \.self) { item in
                Text(item)
                    .border(Color.red)
            }
        }

        // The frame modifier allows the view to expand horizontally
        HStack {
            ForEach(data, id: \.self) { item in
                Text(item)
                    .frame(maxWidth: .infinity)
                    .border(Color.red)
            }
        }
    }
    }
}

比较使用.帧修改器
