You can also do it without AVFoundation and it is in my opinion an easier way to implement it using only the UIImagePickerController. There are 3 conditions:

1. Obviously the device needs to have a camera
2. You must hide the camera controls
3. Then simply use the takePicture method from UIImagePickerController

Below is a simple example that you woul typically trigger after a button push

- (IBAction)takePhoto:(id)sender 
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
    picker.showsCameraControls = NO;
    [self presentViewController:picker animated:YES
                     completion:^ {
                         [picker takePicture];
                     }];
}
