[ios] Base64 Decoding in iOS 7+

I have Encoded text(NSString) using NSData Class new API which is Added in iOS7.

using this

- (NSData *)dataUsingEncoding:(NSStringEncoding)encoding;  

here is my code

NSString *base64EncodedString = [[myText dataUsingEncoding:NSUTF8StringEncoding] base64EncodedStringWithOptions:0];

NSLog(@"%@", base64EncodedString);

I am looking to decode it

In case you want to write fallback code, decoding from base64 has been present in iOS since the very beginning by caveat of NSURL:

NSURL *URL = [NSURL URLWithString:
      [NSString stringWithFormat:@"data:application/octet-stream;base64,%@",
           base64String]];

return [NSData dataWithContentsOfURL:URL];
