4. Получение от сервера события, подтверждающего успешное соединение.

...

При получении данного события вызывается метод публикации потока ViewController publishStream

languagejsbash
- (void)onConnected:(FPWCSApi2Session *)session {
[_connectButton setTitle:@"STOP" forState:UIControlStateNormal];
// [self changeViewState:_connectButton enabled:YES];
[self publishStream];
}

...

  • имя публикуемого потока
  • вид для локального отображения
  • параметры видео (в примере задается разрешение для публикации с iPad)
