이를 만들기 위해 나는 Github에서 https://github.com/googlecast/CastHelloText-ios 다음 & https://github.com/googlecast/CastVideos-iosGoogle Cast 기기에 제대로 연결하고 맞춤 수신기로 URL을 전송하는 방법은 무엇인가요? 당신이 Google 전송과 관련이있다 코드 내 블록에서 봐 다운로드 한 경우
에서 Google 전송 기준을 사용했다. 이 오류가 발생하는 것을 발견하면 알려 주시기 바랍니다. 이 Xcode 또는 Google Cast 버그 .. 또는 가장 일반적인 오류인지 여부를 솔직하게 알지 못합니다. 인간
에뮬레이터를 시작하면 네트워크에서 활성 Chrome Cast 기기를 찾습니다. 발견되면 전송 버튼이 나타납니다. 캐스트 버튼을 누르면 기능이 chooseDevice()으로 바뀌며 네트워크에있는 장치로 UIAlertController를 표시 한 다음 전송할 장치를 선택할 수 있습니다.
장치를 클릭하면 connectToDevice() 기능으로 이동하여 연결합니다.
연결되면 "deviceManagerDidConnect"라는 다음 함수로 이동해야합니다. 그래서 나는 "Connected"라는 메시지를 얻습니다. 5 초 후에 "Error Domain = com.google.GCKError Code = 2. Network connection timeout"이라는 오류 메시지가 나타납니다. 내가 프로젝트를 다시 만들 때 나는 다른 결과를 얻는다 .. "deviceManagerDidConnect"이후에 이제는 "didConnectToCastApplication"함수로 가고 그 것이 처음에는 발생하지 않았다. 이 버그입니까 아니면 내가 잘못하고있는 거지?
내가 "deviceManagerDidConnect"로 가고 나서 "didConnectToCastApplication"기능을 수행 할 것으로 예상됩니다. 그 후 WKWebView를 캐스팅하고 싶습니다. 아직 지원되지 않았습니다. 그래서 저는 Textfield에 내가 준 URL을 캐스팅하고 싶습니다.
어떤 제품 버전을 사용하고 있습니까? 어떤 운영 체제 에서요?
GoogleCastSDK-2.5.1-출시, OS X 요세미티 10.10.1 엑스 코드 버전 6.1.1 (6A2008a)
