Made quick test of these 2 +1 HTML5 renderers on iOS running inside iOS app in the WebView, that is without Nitro acceleration. All run on iPad Air
Leaflet 0.7 : great , works fine, everywhere, doesn’t load while dragging map (on mobile only) , runs on Microsoft Surface too.
OpenLayers 3 beta 1 : runs fine too, loads map during dragging, seems like smaller framerate, can over zoom OSM, doesn’t run in Microsoft Surface well.
Seznam Mapy Api v 4 – proprietary renderer from Seznam , bad rendering on iOS, missing tiles, nice map sources
Videos and original web pages used: – screencasted by AirPlay – that is directly from iPad Air:
