Stop iCarousel labels from scrolling - ios

Question

All my labels, done button and back button are scrolling within my icarousel. Is there a way to stop them from moving with the swipe gesture or are they inherently fixed? Or is it a case of taking them out of the function all together?

Answer 1

The label should be above the iCarousel to do what you want, not inside the views of the carousel.
