you'll need to download the html of the site, then parse it for the <code>&lt;title&gt;</code> tag (which gives you the title) 

and the <code>&lt;link rel="icon" ... &gt;</code> tag which gives you the Favicon.
<a href="https://en.wikipedia.org/wiki/Favicon" rel="nofollow">Wikipedia article on Favicon link</a>

Note that neither the title, nor the favicon are guaranteed to exist, though most sites do provide a title, and most major ones to provide a Favicon.

Here is the easiest way to find the favicon icon of URL

<pre><code>NSString *myURLString = @"http://www.google.com/s2/favicons?domain=www.facebook.com";
NSURL *myURL=[NSURL URLWithString: myURLString];
NSData *myData=[NSData dataWithContentsOfURL:myURL];

UIImage *myImage=[[UIImage alloc] initWithData:myData];
</code></pre>

Swift Version:

<pre><code>let myURLString = "http://www.google.com/s2/favicons?domain=www.facebook.com"
let myURL = NSURL(string: myURLString)!
let myData = NSData.dataWithContentsOfURL(myURL)
let myImage = UIImage(data: myData)!
</code></pre>

May this helps lot

The other answers are correct, however it's worth noting that a favicon is either 16x16 pixels or 32x32 pixels. This is probably not sufficient for the size and resolution you wish to achieve.

There is no textbook way to achieve this, but one way could be to send a request to google for the website title + " icon" (for example "Facebook icon"), and pick the first result.

As for the title of the website, if you're looking for the title displayed in your browser when you enter the website you have to parse the html looking for the <code>&lt;title&gt; &lt;/title&gt;</code> tag.

Achieving both of this could prove challenging, but it's definitely not impossible. There might be some sort of service out there that provides this, but not to my knowledge.
