TabView
似乎伸展到了它的最大高度,但我希望它尽可能地缩短到它需要的高度,而不是空白处。即使周围有 Spacer
个视图,它看起来也是这样:
struct ContentView: View {
var body: some View {
Text("Some text")
Text("Some text")
Text("Some text")
Spacer()
TabView {
GroupBox(label: Text("This is the title 1")) {
Label("Some item 1", systemImage: "checkmark.circle.fill")
Label("Some item 2", systemImage: "checkmark.circle.fill")
Label("Some item 3", systemImage: "checkmark.circle.fill")
Label("Some item 4", systemImage: "checkmark.circle.fill")
}
.padding()
GroupBox(label: Text("This is the title 2")) {
Label("Some item 1", systemImage: "checkmark.circle.fill")
Label("Some item 2", systemImage: "checkmark.circle.fill")
Label("Some item 3", systemImage: "checkmark.circle.fill")
Label("Some item 4", systemImage: "checkmark.circle.fill")
}
.padding()
GroupBox(label: Text("This is the title 3")) {
Label("Some item 1", systemImage: "checkmark.circle.fill")
Label("Some item 2", systemImage: "checkmark.circle.fill")
Label("Some item 3", systemImage: "checkmark.circle.fill")
Label("Some item 4", systemImage: "checkmark.circle.fill")
}
.padding()
}
.tabViewStyle(PageTabViewStyle())
.background(Color.yellow)
Spacer()
Text("Some text")
Text("Some text")
Text("Some text")
}
}
有没有办法动态地将高度收紧到孩子们需要的高度?

使用.frame( height: .leastNormalMagnitude)
.tabViewStyle(PageTabViewStyle())
.background(Color.yellow)
.frame( height: .leastNormalMagnitude)
页面索引涵盖了视图。您可能需要给 GroupBoxes 一个 40-50 点的填充底部或更改 indexViewStyle 的背景。
.indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always))
