iframe scrolling on the iphone

Question

I was aware of multiple scrolling libraries (TouchScroll, iScroll) for the iPhone/iOS due to its inability (???) to support overflow:scroll . However, I was not aware (and I am looking for confirmation) that IFRAMEs don't really work either. It appears that the iframe doesn't respect any attempt to give it a fixed size and always just resizes itself to its content. Am I correct on this? Is the only way to scroll an IFRAME to place it inside a block element with the overflow CSS property set and then to use a lib like the aforementioned?

Answer 1

simply adding...

overflow-y:auto; 
-webkit-overflow-scrolling:touch;

to a div around my iframe worked for me

Answer 2

You can scroll any content which is set to overflow:auto by touching with two fingers and dragging. Don't put iFrame inside a div with overflow:auto, and instead set the iframe to overflow:auto itself. Unfortunately, iframe scrolling is very choppy, regardless of content or device, so the best solution is to find a way to make your content fit into one long page, with "top" & "bottom" view divs set to follow the viewport (if this is the effect you're going for.)
