I have now tried three kiosk apps which use UIWebView and two which use WKWebView. Both WKWebView apps, Kiosk Pro and Xstand work perfectly with HYPE (except that Kiosk Pro currently has an iframes bug and Xstand has been discontinued).
However none of the three UIWebView based kiosk apps have worked with HYPE and all have exactly the same problem. Clicking on a button in HYPE doc which loads a the url for another HYPE doc does not act as it should.
So for example, I’ll have a hype doc with nothing at all in it except a single button and a graphic. That button is just a link to a second hype html doc. The second hype doc has a button which links to third hype html doc.
In any of the UIWebView apps, clicking on the button in hype doc one, jumps straight to hype doc three. Even though there is no link to hype doc three present in hype doc one. This can only mean that when hype doc two loads (which has the link to hype doc three), the link to hype doc three is loaded (without out anyone pressing the link button).
If the link in hype doc one is to a hype doc which only contains a number of scenes but no external links, then when doc two loads, it moves to a different scene within that doc (you can see the fade transition just after the doc loads) again without any user interaction.
What’s even stranger is that if you have three buttons with links in doc one, it will randomly choose one of the three links to jump to, it’s not the same every time. Same thing with scene changes if the link in doc one is to a doc with scenes it will randomly choose a different scene to move to each time you tap the link.
This same thing happens with all three UIWebView apps. It also happens in Kiosk Pro when you switch to UIWebView (Kiosk Pro offers both UIWebView and WKWebView)
But everything works perfectly in WKWebView.
All the links and scene transitions are done using the HYPE inspector, I’m not doing anything fancy or hand coding links or transition changes or anything.
Hence my conclusion that HYPE is not compatible with UIWebView but only with WKWebView at least on iPads with OS 11.
