How to download a web page data in Objective-C and wait until JavaScript is executed?

I try some like that:

NSString *url = @"http://www.example.com";
NSURL *urlRequest = [NSURL URLWithString:url];
NSError *err = nil;

NSString *html = [NSString stringWithContentsOfURL:urlrequest encoding:NSUTF8StringEncoding error:&err];

This returns the html to me perfectly, but it does not return the data that is created from JavaScript, for example graphics and stuff.

Javascript is executed by the browser not the server. When you make a request to the server for a document it processes that request and returns the html/js/css relevant to that page. The browser then executes the javascript locally to do whatever it is it is meant to do, i.e. create images, load ajax data etc.

Your C code is pulling the raw html/js from the server. This is why you are not getting the images etc you expected.
