how to add another image or animation in iOS camera

Question

Just like Häagen-Dazs' App, I think it just add an animation before the photo iPhone is taking. I have checked UIImagePickerController and it didn't say how to add another picture or animation before the image. I just want to add some interesting things in front of the scene that I'm taking. Could anyone provide any tutorial? Thanks.

add you custom UIView with animation like this into ImagePickerView

_imagePickerCamera.sourceType = UIImagePickerControllerSourceTypeCamera;
                             _imagePickerCamera.delegate = self;
                             _imagePickerCamera.showsCameraControls = NO;
                             _imagePickerCamera.navigationBarHidden = YES;
                             _imagePickerCamera.toolbarHidden = YES;
                             _imagePickerCamera.wantsFullScreenLayout = YES;

                             //create an overlay view instance
                             OverlayView *overlay = [[OverlayView alloc]
                                                     initWithFrame:self.view.bounds];
                             //set our custom overlay view
                             _imagePickerCamera.cameraOverlayView = overlay;
                             overlay.captureButton.frame = CGRectMake(self.view.frame.size.width/2 - 30, self.view.frame.size.height - 60, 60, 60);
                             [overlay.captureButton addTarget:self action:@selector(captureImageWithButton:) forControlEvents:UIControlEventTouchUpInside];
                             [self performSelector:@selector(presentCameraView) withObject:nil afterDelay:0.0f];
