How to get the current image?

[kxvn-lx]

I wanted to update a label that I placed inside a custom DTPhotoViewerController everytime user swipes to reveal new photo. I stored the data to the image's identifier. How can I access the current presented image?

I tried self.imageView.image but it returns only the first image every time.

Edit:
Yes I did try to follow the example but I wanted to hide/unhide this label (just like the close and save button from the example) along with other elements that I've placed.
