how to retain values in the following method?

@interface SignDocumentController : UIViewController<NSXMLParserDelegate> {
    NSMutableString *signFaxString;
    NSString * messageId;
    NSMutableData *xmlData;
    NSURLConnection *connectionInprogress;
    NSURLConnection *connectionInprogress2;


    NSString * annotationKey;

    NSString *firstName;
    NSString *lastName;
    NSString *date;
    NSString *signature;


    IBOutlet UIImageView *image;
}

@property(nonatomic,retain)UIImageView * image;


@end

-(void)parser:(NSXMLParser *)parser
didStartElement:(NSString *) elementName
 namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
   attributes:(NSDictionary *)attributeDict
{

    if ([elementName isEqual:@"SignatureInfo"]) {

        signFaxString = [[NSMutableString alloc]init]; 

        firstName = [attributeDict objectForKey:@"FirstName"];
        lastName = [attributeDict objectForKey:@"LastName"];
        date = [attributeDict objectForKey:@"Date"];
        signature = [attributeDict objectForKey:@"Signature"];
    }

    if ([elementName isEqual:@"AddAnnotationResult"]) {
        signFaxString = [[NSMutableString alloc]init]; 
    }


}

the values for firstName, lastName, date, signature do not stay and I get an error when I try accessing firstName, lastName ETC in a different method:

[CFString respondsToSelector:]: message sent to deallocated instance 0x4ec63b0

I have tried using :

firstName = [NSString stringWithString attributeDict objectForKey:@"FirstName"];

but that does not work either. I know this is a silly question but I could use some help.

Thanks

you could also declare the firstName and others as property and retain . As below 

@property(nonatomic,retain)NSString* firstName;
@property(nonatomic,retain)NSString* lastName;    
@property(nonatomic,retain)NSString* date;
@property(nonatomic,retain)NSString* signature;

And in .m class.

@synthesize firstName,date,lastName,signature;

and release them in dealloc function.

Use with self all your property variable in you class.

self.firstName = [NSString stringWithString:attributeDict objectForKey:@"FirstName"];

EDITED:

Also consider @bbum comment ..

To retain it, just send a retain message to the object.

firstName = [[attributeDict objectForKey:@"FirstName"] retain];

release it later.
