下面是可重现的小代码;
正如您在运行演示代码时所Element
看到的那样Color.blue
,根据ZStack
. 顺便说一句,我也玩过zIndex
修改器,但仍然没有运气。你们提供什么解决方案?谢谢大家。
struct ContentView: View {
var body: some View {
GeometryReader { gr in
ZStack {
Color.blue.opacity(0.3)
.aspectRatio(1, contentMode: .fit)
.frame(width: gr.size.width)
VStack {
Spacer()
ScrollView(.horizontal) {
HStack {
ForEach(1...15, id: \.self) { (idx) in
Element(index: idx)
}
}
.padding()
}
.background(Color.secondary.opacity(0.3))
}
}
}
}
}
struct Element: View {
@State private var dragAmount = CGSize.zero
var index: Int
var body: some View {
Rectangle()
.frame(width: 80, height: 80)
.overlay(Text("\(index)").bold().foregroundColor(.white))
.offset(dragAmount)
.gesture(
DragGesture(coordinateSpace: .global)
.onChanged {
self.dragAmount = CGSize(width: $0.translation.width, height: $0.translation.height)
}
.onEnded { _ in
self.dragAmount = .zero
}
)
}
}
