Try to use like this..First you need to get this base64 library

https://github.com/l4u/NSData-Base64

And then import this file

   #import "NSData+Base64.h"

NSData *data = [NSData dataFromBase64String:baseString];

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

I hope it helps.
