item

A binding to an optional source of truth for the sheet. シートに対するある随意の信頼できる情報源へのあるバインディング。 When item is non-nil, the system passes the item’s content to the modifier’s closure.

Discussion 議論

Use this method when you need to present a modal view with content from a custom data source. The example below shows a custom data source InventoryItem that the content closure uses to populate the display the action sheet shows to the user:


struct ShowPartDetail: View {
    @State var sheetDetail: InventoryItem?
    var body: some View {
        Button("Show Part Details") {
            sheetDetail = InventoryItem(
                id: "0123456789",
                partNumber: "Z-1234A",
                quantity: 100,
                name: "Widget")
        }
        .sheet(item: $sheetDetail,
               onDismiss: didDismiss) { detail in
            VStack(alignment: .leading, spacing: 20) {
                Text("Part Number: \(detail.partNumber)")
                Text("Name: \(detail.name)")
                Text("Quantity On-Hand: \(detail.quantity)")
            }
            .onTapGesture {
                sheetDetail = nil
            }
        }
    }


    func didDismiss() {
        // Handle the dismissing action.
    }
}


struct InventoryItem: Identifiable {
    var id: String
    let partNumber: String
