第一种：得到内容的实际高度：
- (void)webViewDidFinishLoad:(UIWebView*)wb{
   CGFloat documentWidth = [[wb stringByEvaluatingJavaScriptFromString:@"document.getElementById('content').offsetWidth"] floatValue];

    CGFloat documentHeight = [[wb stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"content\").offsetHeight;"] floatValue];

    NSLog(@"documentSize = {%f, %f}", documentWidth, documentHeight);

}
}
第二种：得到了将内容显示完整后的webView的尺寸(包含UIEdgeInsets)
- (void)webViewDidFinishLoad:(UIWebView*)wb{
CGRect frame = wb.frame;

    frame.size.width = 768;

    frame.size.height = 1;

    //wb.scrollView.scrollEnabled = NO;

    wb.frame = frame;

    frame.size.height = wb.scrollView.contentSize.height;

    NSLog(@"frame = %@", [NSValue valueWithCGRect:frame]);

    wb.frame = frame;

}
