This is fairly simple. First, you'll need to obtain height of the webpage:

NSInteger height = [[webView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight;"] intValue];

Now you have the height of the document stored in the height variable. To scroll to bottom you have to use javascript again:

NSString* javascript = [NSString stringWithFormat:@"window.scrollBy(0, %d);", height];   
[webView stringByEvaluatingJavaScriptFromString:javascript];

Of course you need to call them in proper moment. That is

– webViewDidFinishLoad:(UIWebView *)webView

method of your webview delegate.
