How cam I make the Camera View to open faster?

I use the iOS CameraViewController TGCameraViewController. It works great. My problem is that the camera view (i.e., when you run the example and hit the "capture image" button) view takes a very long time to be initialized and ready for the user. The AVFoundation is used.

Is there a way to make the camera view appear much faster in the state where the user can capture a photo?
