Before IOS5 I could cause a PDF within a UIWebView to scroll using Javascript. How do I do this under IOS5?

Question

On previous versions of IOS the following code works

- (void)webViewDidFinishLoad:(UIWebView *)webView { 
int height = ([self.page intValue] - 1) * pageHeight;
    if (isProCards)
        height = ([self.page intValue] - 1) * proPageHeight;
NSString *script = [NSString stringWithFormat:@"window.scrollTo(0, %d);", height];
[self.web stringByEvaluatingJavaScriptFromString:script];
}

It no longer works on IOS5. Does anyone know any other way of getting a webview to scroll when displaying a PDF?

Thanks,

Joe

PS I have confirmed that javascript still runs, its just that scrolling doesn't work.

Answer 1

The UIScrollView is exposed in IOS5, this means that you can do this:

[web.scrollView setContentOffset:CGPointMake(0, offset)];

The only caveat is that this can't be called from the webViewDidFinishLoad method. You have to use an NSTimer to execute the code after the web view has loaded and is scrollable.
