WatchOS 3中的本地通知 [英] Local Notification in WatchOS 3

问题描述

我正在使用WatchOS 3 Beta，并尝试在手表上启动本地通知.该接口只是一个按钮，该按钮在下面的代码中调用"buttonPushed"方法.该应用程序运行正常，但我从未收到通知.对于WatchKit应用程序，该应用程序结构是Xcode 8中的默认结构.

I'm using the WatchOS 3 beta and trying to initiate a local notification on the watch. The interface is just one button which calls the "buttonPushed" method in the code below. The app runs fine but I never get a notification. The app structure is the default from Xcode 8 for a WatchKit app.

此代码在WatchKit扩展的InterfaceController.swift文件中

This code is in the InterfaceController.swift file of the WatchKit extension

我错过了完全显而易见的东西吗?

Am I missing something totally obvious?

@IBAction func buttonPushed() {
        sendMyNotification()
    }

    func sendMyNotification(){
        if #available(watchOSApplicationExtension 3.0, *) {

            let center = UNUserNotificationCenter.current()

            center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
                // Enable or disable features based on authorization.
            }


            let content = UNMutableNotificationContent()
            content.title = NSString.localizedUserNotificationString(forKey: "Hello!", arguments: nil)
            content.body = NSString.localizedUserNotificationString(forKey: "Hello_message_body", arguments: nil)
            content.sound = UNNotificationSound.default()
            content.categoryIdentifier = "REMINDER_CATEGORY"
            // Deliver the notification in five seconds.
            let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
            let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger)

            // Schedule the notification.

            center.add(request ,withCompletionHandler: nil)



        } else {
            // Fallback on earlier versions
        }


    }

推荐答案

根据此.您应该每次为请求指定一个唯一的新标识符.

According to this. You should specify a unique and new identifier for request each time.

我的:

let id = String(Date().timeIntervalSinceReferenceDate)
let request = UNNotificationRequest(identifier: id, content: content, trigger: trigger)
