It's not in a standard library, you need to declare and implement additional category to make it work.

@interface NSString (Base64)
- (NSString *)base64EncodeData;
@end

@implementation NSString (Base64)
- (NSString *)base64EncodeData
{
    return .. do something with self to make a base64 encoded string ..;
}
@end
