Decode a Base64 string in objective-c

Question

I'm new in objecive-C and i would like to decode a NSString encoded in Base64.

Have you any idea to help me?

NSString encoded:

eyJjbGUiOiJwOW5oOTk3eDRxdhpnZzciLCJ1cmwiOiJtbGtqcW1sa3FzbWxmbXFsanFkln0

NSString i try to find:

{"cle":"p9nh997x4qvgg7","url":"mlkjqmlkqsmlfmqljqd}

Now I ask OP and myself too: I'm wondering whether it would have been ***really so much friggin' difficult to google "Base-64 Objective-C"?*** — , Feb 01 '13 at 14:56
LOL @Almo went to google, typed "Decode Base64 Objective-C" and this page was the first result! — PassKit, Apr 16 '13 at 05:46

Create NSData from the string:

NSData *data = [NSData dataFromBase64String:string];

convert that data to a string

NSString *convertedString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

Thank you for your help! – user2032850 Feb 11 '13 at 08:27
Just one rectification : it's "NSUTF8StringEncoding" and not "NSUTF8Encoding". – user2032850 Feb 11 '13 at 08:45
ah right, sorry. i rely on auto-complete too much i guess – wattson12 Feb 11 '13 at 10:43
