I have list items in SwiftUI, and when I delete list items I want to delete after alert menu, like
"do want to delete your list items, ""yes" or "no"
is it possible?
struct MyView: View {
@State private var selectedUsers: MyModel?
var body: some View {
ScrollView(.vertical, showsIndicators: false, content: {
VStack(content: {
ForEach(datas){ data in
MyRowView(data: data)
.contextMenu {
Button(action: {
self.delete(item: data)
}) {
Text("delete")
}
}
.onTapGesture {
selectedUsers = data
}
} .onDelete { (indexSet) in
self.datas.remove(atOffsets: indexSet)
}})
})}
private func delete(item data: MyModel) {
if let index = datas.firstIndex(where: { $0.id == data.id }) {
datas.remove(at: index)
}
}}
In the delete action you set a @State bool to true, this triggers e.g. a ConfirmationDialog – and only after confirming there, you really delete:
} .onDelete { (indexSet) in
confirmDelete = true // a @State var Bool
}})
.confirmationDialog("Do you really want to delete?", isPresented: $confirmDelete) {
Button("Delete", role: .destructive) {
selectedUsers.remove(atOffsets: indexSet)
}
Button("Cancel", role: .cancel) { }
}
