NSString *decodeString = @"Raja";

NSData *encodeData = [decodeString dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64String = [encodeData base64EncodedStringWithOptions:0];
NSLog(@"Encode String Value: %@", base64String);

NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:base64String options:0];
NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];

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.
