What app is using my Camera on my iPhone?

In “Settings,” tap “Privacy.” In “Privacy,” tap “Camera.” After that, you'll see a list of apps that have asked you for camera access in the past. Apps that currently have access to your iPhone camera will have a green “on” switch beside them.

UIImagePickerController has a takePicture method that can be called programmatically.
