How to display a base64 image within a UIImageView?

I got this Base64 gif image:

R0lGODlhDAAMALMBAP8AAP///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAACH5BAUKAAEALAAAAAAMAAwAQAQZMMhJK7iY4p3nlZ8XgmNlnibXdVqolmhcRQA7

Now I want to display this Base64 String within my IPhone App.

I could get this working by using the WebView:

aUIWebView.scalesPageToFit = NO;
aUIWebView.opaque = NO;
aUIWebView.backgroundColor = [UIColor clearColor]; 
[aUIWebView loadHTMLString:
  @"<html><body style=""background-color: transparent""><img src=""data:image/png;base64,R0lGODlhDAAMALMBAP8AAP///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAUKAAEALAAAAAAMAAwAQAQZMMhJK7iY4p3nlZ8XgmNlnibXdVqolmhcRQA7"" /></body></html>"
 baseURL:nil];

Is it possible to do the same thing by using the UIImageView?

Very old question, but as of iOS7 there is a new, much easier way to do so, hence I'm writing it here so future readers can use this.

NSData* data = [[NSData alloc] initWithBase64EncodedString:base64String options:0];
UIImage* image = [UIImage imageWithData:data];

Very easy to use, and will not hit the 2048 byte size limit of a URL.

Swift 4+

let base64EncodedString = "" // Your Base64 Encoded String
if let imageData = Data(base64Encoded: base64EncodedString) {
                let image = UIImage(data: imageData)
                self.imageView.image = image
            }
