我目前正在尝试使用SwiftUI和Firebase开发一个简单的ToDoList应用。该应用程序具有唯一的待办事项列表,对于每个待办事项列表,用户应该可以添加多个待办事项。我已经有一个类,用户可以用来创建新的待办事项列表,现在我想添加将待办事项添加到这些列表中的功能。
我已经拥有的POJO类:
import Foundation
import FirebaseDatabase
struct ToDoList: Identifiable {
let ref: DatabaseReference?
let key: String
let todoName: String
let priority: Int
let type: String
var dueDate = DateFormatter.localizedString(from: Date(), dateStyle: .short, timeStyle: .short)
let id: String
init(todoName: String, priority: Int, type: String, dueDate: String, key: String = "") {
self.ref = nil
self.key = key
self.todoName = todoName
self.priority = priority
self.type = type
self.dueDate = dueDate
self.id = key
}
init?(snapshot: DataSnapshot) {
guard
let value = snapshot.value as? [String: AnyObject],
let todoName = value["todoName"] as? String,
let priority = value["priority"] as? Int,
let type = value["type"] as? String,
let dueDate = value["dueDate"] as? String
else {
return nil
}
self.ref = snapshot.ref
self.key = snapshot.key
self.todoName = todoName
self.priority = priority
self.type = type
self.dueDate = dueDate
self.id = snapshot.key
}
func toAnyObject() -> Any {
return [
"todoName": todoName,
"priority": priority,
"type": type,
"dueDate": dueDate
]
}
}
我要显示在Firebase Realtime数据库中的结构如下:
如何更改我的POJO类以使该功能正常工作?
