Resize UIScrollView while Zooming

[thelightforce]

Hi there

How can i change the size of a scrollview while zooming? I need that for the following reasons:

Basically i'd like to have a Scrollable view which has a zoomable image on top and some NOT zoomable html text below. Therefor i've used a scrollview as the main container. Inside this container there is another scrollview containing the imageview and below is a webview which displays the html text.

So i want the inner scrollview to to change its own height when zooming the image. Like this the whole content is vertically scrollable from the main scrollview. The image's content would then only need to be scrolled horizontally as the the image's height is fully visible within the content of the main scrollview.

It's like when reading an email in the mobile mail app except that there is the non-zoomable view on top (the from, cc, subject fields) and the zoomable content below (email content).

Does anyone know how to achieve that?

Ok, guys, I found a «solution» but this is not very elegant.
The view which is transformed by UIScrollview can override (void)setTransformCGAffineTransform) which is called repeatedly while zooming. there you can handle your «onZoom» events. If anyone has a better solution I'd love to hear it.

Cheers
