Access Publisher Object

Utilizing the Page class through the constructor, access the publisher object by looking up the element by the id that you supplied in the view.

import {TNSOTSession, TNSOTPublisher} from 'nativescript-opentok';

private publisher: TNSOTPublisher;

constructor(private page: Page) {
    super();
    this.session = TNSOTSession.initWithApiKeySessionId(this._apiKey, this.sessionId);
    this.publisher = <TNSOTPublisher> this.page.getViewById('publisher');
    this.initPublisher();
}

initPublisher() {
    this.session.connect(this.publisherToken);
    this.publisher.publish(this.session, '', 'HIGH', '30');
}

Notice the additional parameters with this line:

this.publisher.publish(this.session, '', 'HIGH', '30');
