I want to set the webView frame height if we know the height before loading. The string which is returning from given method is in piexls or what.

Sorry not to mention it. It's the height of the content in pixels. When you have that value you can set your webview frame height. I think there's no way to know the height before loading the page.

Sorry, Thanks for your response, But problem not solved.

The pixels I am getting is to large like 517, 233, if the content is only one line code

Does your problem is that you don't want to display the webview before knowing the exact size?

Even after loading i want to change the webview frame height, How can I

If you are loading page from a string you have to be sure it is a correct HTML document. This works:NSString * html = @"<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"><html xmlns=\"http://www.w3.org/1999/xhtml\" lang=\"it\" dir=\"ltr\"><html><head><title>aaaa</title></head><body>Test!</body></html>";
