iPhone UIWebView height

Does anyone know if this solution can be approved by Apple submission app?

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    CGFloat webViewHeight = 0.0f;
    if (self.subviews.count > 0) {
        UIView *scrollerView = [self.subviews objectAtIndex:0];
        if (scrollerView.subviews.count > 0) {
            UIView *webDocView = scrollerView.subviews.lastObject;
            if ([webDocView isKindOfClass:[NSClassFromString(@"UIWebDocumentView") class]])
                webViewHeight = webDocView.frame.size.height;
        }
    }
}

Thanks. Hami.

Implement the UIWebViewDidfinishLoad delegate method and use the following code

Hi ,

You can use the following methods to solve your problem.

For getting the pageOffset:

int pageYOffset = [[webViewObj stringByEvaluatingJavaScriptFromString:@"window.pageYOffset"] intValue];

For getting the total scroll height of a webpage:

int scrollHeight = [[webViewObj stringByEvaluatingJavaScriptFromString:@"document.documentElement.scrollHeight"] intValue];

For scrolling the webpage to a particular offset:

[webViewObj stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.body.scrollTop = %d",scrollHeight ]];

Rather than messing around with private classes that may change and break your app, why not use -stringByEvaluatingJavaScriptFromString: to resize the web page with javascript?
