NSData from NSKeyedArchiver to NSString

Question

I\'m trying to convert NSData generated from NSKeyedArchiver to an NSString so that I can pass it around and eventually convert it back to NSData. I have to pass this as a strin

Answer 1

What you want is:

id obj;

NSData * data     = [NSKeyedArchiver archivedDataWithRootObject:obj];
NSString * string = [data base64EncodedString];

And then the other way around

NSString * string;

NSData * data    = [NSData dataFromBase64String:string];
id obj = [NSKeyedUnarchiver unarchiveObjectWithData:data]

You can add base64EncodedString and dataFromBase64String: with the NSData category available here NSData+Base64 but it is now included by default
