Swift 美团众包抢单程序示例 - iOS 应用开发

以下是一个简单的 Swift 代码示例，展示如何在 iOS 应用中开发美团众包抢单程序。

import UIKit

class Order {
    var orderID: String
    var restaurant: String
    var customer: String
    var orderTime: Date
    
    init(orderID: String, restaurant: String, customer: String, orderTime: Date) {
        self.orderID = orderID
        self.restaurant = restaurant
        self.customer = customer
        self.orderTime = orderTime
    }
}

class DeliveryPerson {
    var name: String
    
    init(name: String) {
        self.name = name
    }
    
    func acceptOrder(order: Order) {
        print('Delivery person (name) accepted order (order.orderID)')
    }
}

class OrderManager {
    var orders: [Order]
    var deliveryPersons: [DeliveryPerson]
    
    init(orders: [Order], deliveryPersons: [DeliveryPerson]) {
        self.orders = orders
        self.deliveryPersons = deliveryPersons
    }
    
    func displayOrders() {
        for order in orders {
            print('Order ID: (order.orderID)')
            print('Restaurant: (order.restaurant)')
            print('Customer: (order.customer)')
            print('Order Time: (order.orderTime)')
        }
    }
    
    func assignOrder(orderID: String, to deliveryPerson: DeliveryPerson) {
        for order in orders {
            if order.orderID == orderID {
                deliveryPerson.acceptOrder(order: order)
                orders = orders.filter { $0.orderID != orderID }
                return
            }
        }
        
        print('Order not found')
    }
}

let order1 = Order(orderID: '123', restaurant: 'Restaurant A', customer: 'Customer 1', orderTime: Date())
let order2 = Order(orderID: '456', restaurant: 'Restaurant B', customer: 'Customer 2', orderTime: Date())

let deliveryPerson1 = DeliveryPerson(name: 'John')
let deliveryPerson2 = DeliveryPerson(name: 'Jane')

let orderManager = OrderManager(orders: [order1, order2], deliveryPersons: [deliveryPerson1, deliveryPerson2])

orderManager.displayOrders()

orderManager.assignOrder(orderID: '456', to: deliveryPerson1)

orderManager.displayOrders()

这个程序包含了Order（订单）类，DeliveryPerson（配送员）类和OrderManager（订单管理器）类。订单包含订单ID、餐厅、顾客和订单时间等信息。配送员可以接受订单，订单管理器可以显示订单和将订单分配给配送员。

你可以根据自己的需求对代码进行修改和扩展。
