Ios &引用；Onesignal for Voip推送“；及；Firebase云消息传递“；don'；我们不能一起工作

我正在集成由“实时数据库”中的更新触发的“Firebase云消息传递”，在与一个用于向IOS设备发送Voip推送通知的信号集成之前，它一直工作正常。 发送Voip推送通知的一个信号工作正常

有人知道我的代码发生了什么吗？如果你能在下面更正我的代码，这对我会非常有帮助（即使只是建议，教我如何解决问题也是很大的帮助）

已经尝试在没有Firebase的情况下使用一个信号发送常规推送通知和Voip推送通知，但是一个信号技术支持提到“我们不建议在Voip和常规推送中使用相同的应用程序。”

并在集成一个信号时添加了以下UNNotificationServiceExtension

class NotificationService: UNNotificationServiceExtension {

var contentHandler: ((UNNotificationContent) -> Void)?
var receivedRequest: UNNotificationRequest!
var bestAttemptContent: UNMutableNotificationContent?

override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
    self.receivedRequest = request;
    self.contentHandler = contentHandler
    bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

    if let bestAttemptContent = bestAttemptContent {
        OneSignal.didReceiveNotificationExtensionRequest(self.receivedRequest, with: self.bestAttemptContent)
        contentHandler(bestAttemptContent)
    }
}

override func serviceExtensionTimeWillExpire() {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
    if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
        OneSignal.serviceExtensionTimeWillExpireRequest(self.receivedRequest, with: self.bestAttemptContent)
        contentHandler(bestAttemptContent)
       }
    }
}

您应该使用

可用内容

标志

关于Firebase文档，您必须以某种方式传递

content\u available

参数。这对你的情况可能有帮助

您是否检查推送令牌是否发送到fcm服务器？

class NotificationService: UNNotificationServiceExtension {

var contentHandler: ((UNNotificationContent) -> Void)?
var receivedRequest: UNNotificationRequest!
var bestAttemptContent: UNMutableNotificationContent?

override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
    self.receivedRequest = request;
    self.contentHandler = contentHandler
    bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

    if let bestAttemptContent = bestAttemptContent {
        OneSignal.didReceiveNotificationExtensionRequest(self.receivedRequest, with: self.bestAttemptContent)
        contentHandler(bestAttemptContent)
    }
}

override func serviceExtensionTimeWillExpire() {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
    if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
        OneSignal.serviceExtensionTimeWillExpireRequest(self.receivedRequest, with: self.bestAttemptContent)
        contentHandler(bestAttemptContent)
       }
    }
}
