uiwebview slow after javascript call to document.body.innerHTML += someString
After I call 

    NSString* javaScript = [NSString stringWithFormat:@"document.body.innerHTML += '%@';", stringToAppend];
    [self.webView stringByEvaluatingJavaScriptFromString:javaScript];

on my UIWebview scrolling becomes slow and choppy. I assume this is because it is loading new html as it scrolls. 

Is there a way to force it to load all the html at once so that its not so choppy? 

Thanks!
