You can change your image using UILongPressGestureRecognizer.You can add gesture to your cell and you can change your image in hangleLongPress method.

UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
    lpgr.minimumPressDuration = 1.0;  //user must hold for 1 second
    [cell addGestureRecognizer:lpgr];


- (void)handleLongPress:(UIGestureRecognizer *)gestureRecognizer
{
    if (gestureRecognizer.state == UIGestureRecognizerStateBegan)
      {
         // ----------------- Make here image visible ----------
      }

      if (gestureRecognizer.state == UIGestureRecognizerStateEnded)
      {
         // ------------ Make here image invisible ----------
      }
}
