This doesn't seem like a wise idea in practice - doubletap triggers zooming natively on iOS. What is it you're trying to accomplish?
Hi Sarah, I have actually found and an answer and will post shortly. I've even disbaled the web zoom to allow double tap gesture to serve a variety of functions. Stay tuned for the post
Hi Sarah, I was also looking for double tap, check out the Kia See'd car magazine if you can, it's a wonderful interactive car magazine. Lovely parallax scrolling, and on one page has lots of small Polaroid photos that can be dragged around the page and then enlarged with a double tap, another double tap resets the size. It works really well. Though when I read what you said I did then wonder why it would take a double tap to enlarge, but is a single tap too close to a drag? The user may tap by mistake rather than touch and drag? Interesting UI question. Anyway jplbm seems to have found a solution so is it something you can answer? Can we create a double tap in EA? It does seem to work well with drag image around then double tap it to enlarge
