Send UIWebView title to UINavigationBar

问题

I am trying to send the UIWebView page Title to UINavigationBar.

I would also like it if a user clicks on a link the UINavigationBar shows a back button but if on the home page hide the back button.

回答1:

to retrieve the title page into an UIWebView you can use it:

myNavigationBar.title = [myWebView stringByEvaluatingJavaScriptFromString:@"document.title"];

If you want to go back you can do that:

if ([myWebView canGoBack]){
    [myWebView goBack];
}

To know if the user has loaded a new page you must set the UIWebViewDelegate. For more information see the UIWebView Class Reference and the UIWebViewDelegate Protocol Reference

回答2:

As of iOS8 you should just use WKWebView and its title property.
