I got this Base64 gif image:
R0lGODlhDAAMALMBAP8AAP///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAACH5BAUKAAEALAAAAAAMAAwAQAQZMMhJK7iY4p3nlZ8XgmN
Just in case anyone is looking for the Swift code to accomplish this (based on the Objective-C answer provided by Jonathan M), here it is:
var data = NSData (base64EncodedString: base64String, options: NSDataBase64DecodingOptions(0)) var image = UIImage(data: data!)
