I got this Base64 gif image:
R0lGODlhDAAMALMBAP8AAP///wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAACH5BAUKAAEALAAAAAAMAAwAQAQZMMhJK7iY4p3nlZ8XgmN
This Code will display an base64 encoded string as a picture:
NSString *str = @"data:image/jpg;base64,";
str = [str stringByAppendingString:restauInfo.picture];
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:str]];
restauInfo.picture is an NSString which contains the base64 encoded JPG
In my case the Value from "restauInfo.picture" comes from a database
