我使用Sinch进行音频通话，我也使用CallKit。我在应用程序处于后台状态时遇到问题，我通过CallKit呼叫CXProviderDelegate，但是sinch客户端没有活动的来电。请告诉我如何解决这个问题？
final class ProviderDelegate: NSObject, CXProviderDelegate {
private let provider: CXProvider
static let shared = ProviderDelegate()
private override init() {
provider = CXProvider(configuration: type(of: self).providerConfiguration)
super.init()
provider.setDelegate(self, queue: nil)
}
/// The app's provider configuration, representing its CallKit capabilities
static var providerConfiguration: CXProviderConfiguration {
let localizedName = NSLocalizedString("App name", comment: "Name of application")
let providerConfiguration = CXProviderConfiguration(localizedName: localizedName)
providerConfiguration.supportsVideo = true
providerConfiguration.maximumCallsPerCallGroup = 1
providerConfiguration.supportedHandleTypes = [.phoneNumber]
if let iconMaskImage = UIImage(named: "IconMask") {
providerConfiguration.iconTemplateImageData = UIImagePNGRepresentation(iconMaskImage)
}
providerConfiguration.ringtoneSound = "Ringtone.aif"
return providerConfiguration
}
// MARK: Incoming Calls
/// Use CXProvider to report the incoming call to the system
open func reportIncomingCall(uuid: UUID, handle: String, contactID: String, hasVideo: Bool = false, completion: ((Error?) -> Void)? = nil) {
// Construct a CXCallUpdate describing the incoming call, including the caller.
let update = CXCallUpdate()
update.remoteHandle = CXHandle(type: .phoneNumber, value: handle)
update.hasVideo = hasVideo
// Report the incoming call to the system
provider.reportNewIncomingCall(with: uuid, update: update) { error in
if error == nil {

call.handle = handle
SwiftlyChatCallManager.shared.addCall(call)

}
}
}

guard let contact = contactsRealmManager.getContact(sinchIncomingCall.sin.userID) else { return }
let phoneNumber = contact.firstPhoneNumber() ?? ""
completion?(contact.id, phoneNumber)
}
}
}
我也有SinchManager并且它有这个方法
extension SinchManager {
open func activeAudioSession(_ provider: CXProvider, audioSession: AVAudioSession) {
sinch?.call().provider(provider, didActivate: audioSession)
}
}

我解决了这个问题。我将此方法添加到SinchManager
open func relayRemotePushNotification(_ userInfo: [AnyHashable : Any]) {
DispatchQueue.main.async {
guard let result = self.sinch?.relayRemotePushNotification(userInfo) else { return }
guard result.isCall() else { return }
debugPrint("result.isCall()", result.isCall())
}
}
并在此处调用此方法
func pushRegistry(_ registry: PKPushRegistry, didReceiveIncomingPushWith payload: PKPushPayload, for type: PKPushType, completion: @escaping () -> Void) {
guard type == .voIP else { return }
debugPrint("VOIPmanager didReceiveIncomingPushWith")
DispatchQueue.global(qos: .default).async {
SinchManager.default.relayRemotePushNotification(payload.dictionaryPayload)
}
}

在来自https://www.sinch.com/downloads/的Sinch iOS下载包中，有一个参考实现（Sinch CallKit示例应用程序），它显示了通过CallKit框架处理传入调用的大多数用例。请看一下（尽管示例应用程序仍在Objc中）。如果您在Sinch门户网站上为您的应用程序上传了有效的VOIP推送证书，那么安装该应用程序并在iPhone上使用它应该相当容易。
以下是CallKit示例App的演示视频，用于处理前台，后台和锁定屏幕模式的呼叫。
