func actionSheet<T>(item: Binding<T?>, content: (T) -> ActionSheet ) -> some View where T : Identifiable
itemA binding to an optional source of truth for the action sheet.
アクション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 contents to the modifier’s closure. You use this content to populate the fields of an action sheet that you create that the system displays to the user. If item changes, the system dismisses the currently displayed action sheet and replaces it with a new one using the same process.
contentA closure returning the Action you create.
Use this method when you need to populate the fields of an action sheet with content from a data source. The example below shows a custom data source, File, that provides data to populate the action sheet:
struct FileDetails: Identifiable {
var id: String { name }
let name: String
let fileType: UTType
}
struct ConfirmFileImport: View {
var sheetDetail: FileDetails?
var body: some View {
Button("Show Action Sheet") {
sheetDetail = FileDetails(name: "MyImageFile.png",
fileType: .png)
}
.actionSheet(item: $sheetDetail) { detail in
ActionSheet(
title: Text("File Import"),
message: Text("""
Import \(detail.name)?
File Type: \(detail.fileType.description)
"""),
buttons: [
.destructive(Text("Import"),
action: importFile),
.cancel()
])
}
}
func importFile() {
// Handle import action.
}
}
