POHow can you pin a header overtop of a UIScrollView that only scrolls in the x dimension?

copied!<p>I have a UIScrollView that is displaying some graphical data and it has a x axis at the top of the screen. Currently when you scroll down the x axis disappears because it is just a subview of UIScrollView but I want it pinned to the top of the screen at all times so the user can see the x axis values.</p> <p>Typically I would just put this axis ontop of the scroll view, so that it doesn't scroll, but I still need it to scroll along with the UIScrollView whenever a horizontal scroll takes place because the x axis does not entirely fit in the view.</p> <p>I'm not sure how to go about doing this. I've thought about a few approaches.</p> <ol> <li>I could remove the x axis from the ScrollView and then put it in its own UIView and then use the scroll view delegate methods to sync the x axis with the scrollviews new position after and during a horizontal scroll.</li> <li>I could somehow duplicate horizontal scroll events and pass them to the x axis view (which would be another UIScrollView in this case).</li> </ol> <p>I'm hesitant to try number one because I think the animations would be jerky or at the very least out of sync with the horizontal scroll of the scroll view, I would like them to be completely in sync.</p> <p>I'm hesitant to try number two because I'm not sure if that is even possible to do.</p> <p>I'm looking for advice on how to approach this problem (preferably from somebody who has done something similar before).</p> <p>Thanks in Advance!</p>
