How to connect to user's stream in TokBox

问题:

I'm making a 1 on 1 video call app using TokBox. I'm opening a session using this code:

[_session connectWithApiKey:kApiKey token:kToken];

after getting the didConnect message i'm publishing a stream on one user device using this code:

    _publisher = [[OTPublisher alloc] initWithDelegate:self];
    [_publisher setName:@"PublishName"];
    [_session publish:_publisher];
    [self.view addSubview:_publisher.view];
    [_publisher.view setFrame:CGRectMake(0, 0, widgetWidth, widgetHeight)];

What do I need to transfer to the other user in order for him to see what the first user publishes? I tried going through the docs but It's really unclear to me. Do I need a session ID? Publish ID?

Thanks.

Think of sessions as rooms. People connected to the same session will be in the same room so they are able to see each other. Lets say you have 2 iPhones, A and B. After iPhone A calls [_session publish...], iPhone B will get a stream created event with A's video stream. Simply subscribe to that stream and B should be able to see As video.

You probably want to have a streamCreated delegate. In your streamCreated delegate, simply call [session subscribe...] to subscribe to the publishing stream.

For an example, check out the OpenTok HelloWorld Tutorial. Its a simple group video chat where everybody is publishing and subscribing to each other.
