objective c - How to open front/back camera at the same time in iOS developing? -

I want to use the front and rear camera at the same time in iOS development: when I take a photo back After the camera, the front camera can be opened and another can take a photo. By the way, these two photos are in a picture: vertical arrangement.

Has anyone done this before?

UIImagePickerController to take the picture, and to determine which camera is used Is in. / P>

To merge the pictures, I found an example through search (its recommendation in the future)
