How can I enable zoom in on UIWebView which inside the UIScrollView?

Question

Hi,

I have a UIWebView which inside a UIScrollView (scrollview contain another component)

I tried to enable multitouch both on Interface Builder or Programmatic on UIWebView but it still cannot zoom for html, do I need to handle both zoom in at the UIScrollView and UIWebView? Or anything I haven't to set?

Thanks.

Answer 1

You need to implement the viewForZoomingInScrollView method in your controller, or zooming won't do anything. (I don't really know why this should be needed, but there you go.)

For detailed information, see http://developer.apple.com/iphone/library/documentation/WindowsViews/Conceptual/UIScrollView_pg/ZoomZoom/ZoomZoom.html.

You MUST set scalesPageToFit=YES for any pinching and zooming to work on a UIWebView
