折腾:

【已解决】用飞语FYRtcEngineKit去实现基本的iOS间的语音通话

期间,点击 挂断按钮:

结果程序就崩溃了:

FYRtcEngineKitDemo[787:145041] -[FYRtcEngineKitDemo.ViewController onFYRtcEngine:CallEnd:]: unrecognized selector sent to instance 0x17624150

libc++abi.dylib: terminating with uncaught exception of type NSException

相关代码:

    @IBAction func endCallBtnEvent(_ sender: UIButton) {
        //        fyRtcEngine.leaveChannel(nil)
        if (isCalling) {
            fyRtcEngine.endCall(self.endCallCallback)
            self.infoNotice(“挂断通话”)
        } else {
            let dialOption:FYOptionData = FYOptionData()
            dialOption.isRecord = true
            //dialOption.maxDuration = 60 * 60 * 24
            dialOption.maxDuration = 60 * 10
            let otherUid = self.otherTextField.text!
            let selfUid = self.selfTextField.text!
            fyRtcEngine.dialPeer(otherUid, callerUid: selfUid, optionData: dialOption)
            self.infoNotice(“主叫:调用dialPeer”)
        }
        self.isCalling = !self.isCalling
        self.updateCallButtonImage()
    }

但是第一次点击是没有问题的。

通话后,再点击挂断,结果就崩溃了。

试试:

//    @IBAction func endCallBtnEvent(_ sender: UIButton) {

    func endCallBtnEvent(sender: UIButton) {

结果第一次点击就会出错

【总结】

后来继续调试发现:

FYRtcEngineKitDemo[806:149759] *** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[FYRtcEngineKitDemo.ViewController onFYRtcEngine:CallEnd:]: unrecognized selector sent to instance 0x15573fc0’
*** First throw call stack:

错误信息中,是CallEnd函数中,找不到对应的实例而报错

而此处实际上,是没有添加对应的飞语SDK的代理FYRtcEngineKitDelegate的CallEnd

而去加上对应的CallEnd函数:

    func onFYRtcEngine(_ engine: FYRtcEngineKit!, callEnd status: FYRtcEngineStatus!) {
        self.infoNotice(“通话结束: \(statusToShortStr(fyStatus: status))”)
    }

即可解决此问题。
