我正在使用Callkit和Linphone开发iOS voip应用程序.当我收到来电时,系统显示本机电话用户界面,用户接受或拒绝接听电话,当用户点按接听按钮时,呼叫开始但电话用户界面消失.
如何在用户接听电话后保留本机手机用户界面,例如whatsapp吗？
这是我的providerDelegate代码：
func reportIncomingCall(uuid: UUID,handle: String,hasVideo: Bool = false,completion: ((NSError?) -> Void)? = nil) {
// Construct a CXCallUpdate describing the incoming call,including the caller.
let update = CXCallUpdate()
update.remoteHandle = CXHandle(type: .generic,value: handle)
update.hasVideo = hasVideo
// Report the incoming call to the system
provider.reportNewIncomingCall(with: uuid,update: update) { error in
/*
Only add incoming call to the app's list of calls if the call was allowed (i.e. there was no error)
since calls may be "denied" for var@R_404_437@s legitimate reasons. See CXErrorCodeIncomingCallError.
*/
if error == nil {
print("calling")
}
}
}
func provider(_ provider: CXProvider,perform action: CXStartCallAction) {
let update = CXCallUpdate()
update.remoteHandle = action.handle
provider.reportOutgoingCall(with: action.uuid,startedConnectingAt: Date())
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "callStart"),object: self,userInfo: ["uuid":action.uuid])
action.fulfill(withDateStarted: Date())
}
func provider(_ provider: CXProvider,perform action: CXAnswerCallAction) {
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "callStart"),userInfo: ["uuid":action.uuid])
// ACCEPT CALL ON SIP MANAGER
if let voiceCallManager = AppDelegate.voiceCallManager {
voiceCallManager.acceptCall()
}
action.fulfill(withDateConnected: Date())
}
