Swift 没有生成（或接收？）我期望的所有通知

我编写了一个简单的应用程序来接收BLE广告，并为每个收到的广告生成一个通知。问题是我没有看到我收到的每个BLE数据包的通知

设备设置直接影响显示内容。这是我在iPhone上设置的：

• iOS 12.4.1
• 常规->通知->应用程序名称->
• 允许通知：在
• 警报：锁定、通知中心和横幅
• 横幅样式：临时
• 显示预览：始终
• 分组：关闭

应用程序代表：

public func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {

    guard let serviceData = advertisementData["kCBAdvDataServiceData"] as? [CBUUID:Data] else {
      return
    }

    // get the message-specific payload
    guard let payload = serviceData[CBUUID(string: "FDF4")] else {
      return
    }

    // Try to parse this advertisement. 
    let parseResults = self.parsingService.parseData(payload)

    // validate this packet. 
    if self.parsingService.isParseError(parseResults: parseResults, rawBytes: payload.hexEncodedString()) {
      return
    }

    // the packet looks good. Convert it to our internal format
    let newPacket = OEMRecord(parseApiResults: parseResults)

    // filter out a specific message type to reduce chatter
    if (newPacket.getMsgTypeAsInt() == kMessageTypeToListenFor) {
      let serialNumber = newPacket.serialNo
      if (serialNumber == kSerialNumberToListenFor) {

        // we found the device we want!
        let msg = "Found tracker: \(serialNumber)"
        self.logMessage(msg: msg)

        DispatchQueue.main.async { [weak self] in
            // we have received a tracker pkt. Tell the entire app (i.e. pass msg to ViewController)
            NotificationCenter.default.post(name: NSNotification.Name(didReceiveDesiredTracker), object: self, userInfo: ["text": msg])
         }
      }
    }
}

视图控制器

override func viewDidLoad() {        
    super.viewDidLoad()

    // Request permission to send notifications
    notificationCenter.requestAuthorization(options:[.alert, .badge]) { (granted, error) in }

    NotificationCenter.default.addObserver(self,
                                           selector: #selector(processReceiveDesiredTrackerNotification(notification:)),
                                           name: NSNotification.Name(rawValue: didReceiveDesiredTracker),
                                           object: nil)
}

// log the incoming BLE msgs to the console & the GUI
@objc func processReceiveDesiredTrackerNotification (notification: NSNotification) {
    guard let payload = notification.userInfo else { return }     // sanity chk - probably unnecesary

    guard let msg = payload["text"] as? String  else { return }    // ensure we have a payload to display

    // log to console & GUI
    self.logMessage(msg: msg)

    // generate a Local Notification
    self.scheduleNotification(msg: msg)
}


// show a (Local) Notification for the pkt just received
private func scheduleNotification(msg: String) {
    UIApplication.shared.applicationIconBadgeNumber += 1
    let content = UNMutableNotificationContent()
    content.title = "ALARM #\(UIApplication.shared.applicationIconBadgeNumber)"
    content.body = "\(msg) #\(UIApplication.shared.applicationIconBadgeNumber)"
    content.badge = UIApplication.shared.applicationIconBadgeNumber as NSNumber // keep running count of # of pkts received

    let request = UNNotificationRequest(identifier: "BLEScannerNotification", content: content, trigger: nil)
        notificationCenter.add(request)
}

BLE分组以每次突发5-7个完整分组的突发方式到达。突发中的数据包间隔约0.5秒。每一次爆炸间隔几分钟

1） 在控制台中，我看到接收到一个日志消息

2） 但是，我每次突发只收到1个通知。似乎NotificationCenter处理第一个通知，而忽略（或汇总）每个突发中的其余通知

我错过了什么
