Нет видимого @interface для 'RTCPeerConnection' объявляет селектор 'setLocalDescription:'

Question

Я немного смущен тем, что нужно сделать здесь, чтобы включить webRTC в мое приложение. Я следил за этим tutorial на веб-сайте webRTC, чтобы сначала добавить webRTC в мое приложение IOS. Все прошло хорошо до конца, где я столкнулся с этими ошибками. К сожалению, я не могу найти какую-либо информацию в Интернете об этих ошибках или о том, как включить webRTC в IOS.

Конечная цель состоит в том, чтобы иметь кросс-платформенное видеовызовое обслуживание.

Answer 1

Вы получаете ошибку компиляции, потому что с последней версией libjingle, PeerConnection APIs получил изменения. Настройка удаленного например описание изменено ниже апи

[peerconnection setRemoteDescriptionWithDelegate:<#(id<RTCSessionDescriptionDelegate>)#> sessionDescription:<#(RTCSessionDescription *)#>] 

Вы можете проверить apprtc demo приложение предоставляемые Google интегрировать WebRTC APIs в вашем приложении.
