How can I convert my device token (NSData) into an NSString?

This is a little bit shorter solution:

NSData *token = // ...
const uint64_t *tokenBytes = token.bytes;
NSString *hex = [NSString stringWithFormat:@"%016llx%016llx%016llx%016llx",
                 ntohll(tokenBytes[0]), ntohll(tokenBytes[1]),
                 ntohll(tokenBytes[2]), ntohll(tokenBytes[3])];
