In an application I’m working on, I display a UIWebView with a navigation bar. I wanted to display the title of the web page in the navigation bar when I load a page, but there doesn’t appear to be any obvious way to do it.
There’s actually a very easy way to get the title (or any other property) of a page in a web view: stringByEvaluatingJavaScriptFromString:.
In this case, I use the delegate method webViewDidFinishLoad to obtain the page title and set the title of the navigation bar,
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString* title = [webView stringByEvaluatingJavaScriptFromString: @"document.title"];
navbar.title = title;
}
The result looks like this:
