Swift通过通知发送附加数据

// 发送通知
let notificationName = Notification.Name("MyNotification")
let userInfo = ["key1": "value1", "key2": "value2"]
NotificationCenter.default.post(name: notificationName, object: nil, userInfo: userInfo)

// 接收通知
@objc func handleNotification(_ notification: Notification) {
    if let userInfo = notification.userInfo {
        if let value1 = userInfo["key1"] as? String {
            print("Value 1: \(value1)")
        }
        if let value2 = userInfo["key2"] as? String {
            print("Value 2: \(value2)")
        }
    }
}

NotificationCenter.default.addObserver(self, selector: #selector(handleNotification(_:)), name: notificationName, object: nil)
