Discussion
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, FileDetails, that provides data to populate the action sheet:
struct FileDetails: Identifiable {
var id: String { name }
let name: String
let fileType: UTType
}
struct ConfirmFileImport: View {
@State private 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.
}
