How to set scroll position on uiwebview - iphone

Question

I want to go to specify line on my uiwebview loaded.
I tried
[webView stringByEvaluatingJavaScriptFromString:#"window.scrollTo(0.0,
100.0)"];
but it's not working. My webview still start with top of the page.
I just wonder its because I load the UIWebview inside UIView.
Check my code below on my UIView:
- (void)loadView {
webview = [[WebViewDetail alloc]initWithFrame:[UIScreen mainScreen].applicationFrame]; //initialize a mainView is a UIWebVIew
webview.managedObjectContext = self.managedObjectContext;
webview.kitab = self.kitab;
webview.currentPasal = self.pasal;
self.title = [NSString stringWithFormat:#"%# %d", self.kitab, webview.currentPasal];
self.view=webview; //make the mainView as the view of this controller
}
and I put the scroll positioning script on my UIWebView:
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
int height = [[webView stringByEvaluatingJavaScriptFromString:#"document.body.offsetHeight;"] intValue];
NSString* javascript = [NSString stringWithFormat:#"window.scrollBy(0, %d);", height];
[self stringByEvaluatingJavaScriptFromString:javascript];
}
in this case I want to put my uiwebview go to the bottom of the page when the view is loaded.
But it's totally not working, why?
Am I doing it wrong?

Try
webview.scrollView.contentOffset = CGPointMake(0, 100);

Make sure you set the view controller where you have your web view to be a UIWebViewDelegate, and declare this in the #interface of the header file (.h).
[yourWebView setDelegate:self];
Then, in the webViewDidFinishLoad: method, insert this code:
[yourWebView.scrollView scrollRectToVisible:CGRectMake(0, yourWebView.bounds.size.height + 100, 1, 1) animated:NO];
