How to set the Image of an UIImageView with the source attribute URL of a HTML <img> tag?

I am trying to set the image of an UIImageView with the contents of a img tag of a web. The HTML code is similar to this one:

<img style="-webkit-user-select: none; display: block; margin: auto; cursor: zoom-in;" src="https://web.whatsapp.com/pp?t=l&amp;u=34607243225%40c.us&amp;i=1449421118" width="325" height="325">

I tried to use SDWebImage but it is not working. So I suppose I can load a NSData with the HTML src link and decode somehow in my code.

Any tip with this issue please?
