如何关闭CallKit背景绿色通知

Question

我遇到了一个问题，因为呼叫未接通，但是此CallKit UI通知（或任何被称为的呼叫）仍在后台并且无法杀死它。很明显，由于cal未连接，我无法打电话给performEndCallAction，也无法打电话给uuid。

还有其他方法可以杀死/消除这种情况吗？

以下是我的开始通话操作代码。

发生错误时，将记录以下日志：

callButtonTapped

执行通话

在报告电话之前

reportCall之后

// MARK: Call Kit Actions
func performStartCallAction(uuid: UUID, handle: String) {
    let callHandle = CXHandle(type: .generic, value: handle)
    let startCallAction = CXStartCallAction(call: uuid, handle: callHandle)
    let transaction = CXTransaction(action: startCallAction)

    callKitCallController.request(transaction)  { error in
        if let error = error {
            NSLog("StartCallAction transaction request failed: \(error.localizedDescription)")

            // Try ending the call if the green bar disappears
            DispatchQueue.main.async {
                let alert = UIAlertController(title: "Call failed", message: "Something went wrong. Please close app, restart and try again. Contact support if problem persists.", preferredStyle: UIAlertController.Style.alert)
                let okAction = UIAlertAction(title: "Ok", style: UIAlertAction.Style.default) { (action) in

                }
                alert.addAction(okAction)
                alert.view.tintColor = .purpleColour
//                alert.view.layoutIfNeeded() //avoid Snapshotting error
                self.present(alert, animated: true, completion: nil)
            }
            return
        }

        NSLog("StartCallAction transaction request successful")

        let callUpdate = CXCallUpdate()
        callUpdate.remoteHandle = callHandle
        callUpdate.supportsDTMF = true
        callUpdate.supportsHolding = true
        callUpdate.supportsGrouping = false
        callUpdate.supportsUngrouping = false
        callUpdate.hasVideo = false

        print("Before reportCall")
        self.callKitProvider.reportCall(with: uuid, updated: callUpdate)
        print("After reportCall")
    }
}

您必须使用Callkit请求结束交易。可以解决您的问题

let endCallAction = CXEndCallAction(call: uuid)
let transaction = CXTransaction()
callController.request(transaction) { error in
    if let error = error {
        // End call transaction  failed
    } else {
        // End call transaction succeeded. this will hide the green color bar
    }
}
