Detecting smile without taking photo

Question

I wonder if it is possible to check for face/smile/blink using CIDetectorwithout taking photo?

You are just running UIImagePickerController and when face is found you display UIAlert or something else. I know I can take a photo and later check for detections but I'm curious if it is possible to avoid taking picture.

Thanks in advance for answers!

Check out SquareCam, Apple's sample project for detecting facial features in real time using a camera. While it's a bit more complicated that just using a UIImagePickerController, it should be able to handle what you need. Hope that Helps!
