google-cloud-firestore - SwiftUI，列表，.onDelete(执行 : ) and Firestore

Question

我创建了一个能够通过方法删除行的列表:.onDelete (perform:)。

List {
   ForEach(itemList.dataLocation) { item in
      NavigationLink(destination: ListDetails(name: item.nameDB)) {
           ListItem(name: item.nameDB)
      }
   }
   .onDelete(perform: delete)
   .onMove(perform: move)
}


func delete(at offsets: IndexSet) {
        itemList.dataLocation.remove(atOffsets: offsets)
        session.deleteData(id: //id row) //this problem
}

如何将已删除字符串的值传递给函数？建议仍然从该行获取数据。提前致谢!

Answer 1

在删除函数中，offsets 是被删除项目的 IndexSet。通常它是一组元素。

func delete(at offsets: IndexSet) {
  for index in offsets {
    session.deleteData(id: itemList.dataLocation[index].id) // problem solved
  }
  itemList.dataLocation.remove(atOffsets: offsets)
}
