why the latest MAC desktop sdk has no default meeting UI

I integrate latest sdk which is release on 10/30. In the sample project, there is no default big zoom video UI after I start a meeting. Just only a small preview view instead. How can I show the default UI which can be fullscreen with status toolbar.

In the sample project, you need set [[ZoomSDK sharedSDK] initSDK:NO] in AppDelegate.m. Set NO means use Zoom native UI, yes means use customized UI.
