ios - 如何关闭 CallKit 后台绿色通知

Question

我遇到了一个问题，因为调用未连接，但此 CallKit UI 通知(或任何它所调用的)仍保留在后台，我无法终止它。很明显，我无法调用 performEndCallAction，因为 cal 未连接并且我无法获取调用的 uuid。

还有什么可以杀死/解散它？

以下是我的开始调用操作代码。

当错误发生时，日志如下:

callButtonTapped

执行调用

// 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。这会解决你的问题

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
    }
}
