通过在swiftui中向下滑动来限制取消工作表

@State private var isSheetPresented = false

Button("显示工作表") {
    isSheetPresented = true
}

.sheet(isPresented: $isSheetPresented) {
    Text("这是一个工作表")
}

.gesture(
    DragGesture()
        .onChanged { gesture in
            if gesture.translation.height > 0 {
                isSheetPresented = false
            }
        }
)

struct ContentView: View {
    @State private var isSheetPresented = false
    
    var body: some View {
        VStack {
            Button("显示工作表") {
                isSheetPresented = true
            }
        }
        .sheet(isPresented: $isSheetPresented) {
            Text("这是一个工作表")
        }
        .gesture(
            DragGesture()
                .onChanged { gesture in
                    if gesture.translation.height > 0 {
                        isSheetPresented = false
                    }
                }
        )
