UIWebView — load external website, programmatically set initial zoom scale, and allow user to zoom afterwards

Question

Is it possible to do all of the above? SO has given me a great way to set the initial zoom scale here. Namely, to include the following line in my webViewDidFinishLoad met

Answer 1

It looks like the underlying UIScrollView is accessible starting from iOS 5.x.

In webViewDidFinishLoad: you can request a zoom, for example:

[webView.scrollView zoomToRect:CGRectMake(0.0, 0.0, 50.0, 50.0) animated:YES];

This seems to work even with scalesPageToFit set to YES.
