我有一個 ScrollView，當我向上滾動時，螢屏上的內容會向下移動。但我想限制內容可以向下移動的程度。我不希望用戶能夠滾動到頂部的灰色矩形之外。換句話說，我不希望用戶在向上滾動時看到灰色矩形上方的白色區域。我怎樣才能在 SwiftUI 中實作這一點？
import SwiftUI
struct ScrollViewIssue: View {
var body: some View {
ScrollView {
VStack {
Rectangle()
.foregroundColor(.gray)
.frame(height: 200)
Circle()
.frame(width: 300, height: 300)
Circle()
.frame(width: 300, height: 300)
Circle()
.frame(width: 300, height: 300)
Circle()
.frame(width: 300, height: 300)
}
}.ignoresSafeArea()
}
}

您可以從滾動視圖中洗掉“彈跳”效果，例如
UIScrollView.appearance().bounces = false
