I'm developing an iOS 5.0+ app with latest SDK.

I get a very strange error with this code:

- (NSMutableURLRequest*)setupRequestWithService:(NSString*)service andMethod:(NSString*)method
{
    NSString* url = [NSString stringWithFormat:@"%@%@.svc/%@", serverUrl, service, method];

    NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];

    // Set authentication token.
    NSLog(@"???????????? %@", authenticationToken);
    if (authenticationToken == nil)
        NSLog(@"NULL AUTHTOKEN");
    if ([authenticationToken isEqual:[NSNull null]])
        NSLog(@"NSNULL AUTHTOKEN");
    if (request == nil)
        NSLog(@"NULL REQUEST");
    [request addValue:authenticationToken forHTTPHeaderField:REQUEST_HEADER_AUTH_TOKEN];

    return request;
}

This is my log:

???????????? <null>
NSNULL AUTHTOKEN
-[NSNull length]: unrecognized selector sent to instance 0x3b5a5090
    *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull length]: unrecognized selector sent to instance 0x3b5a5090'

It seems that authenticationToken is NULL. But I don't understand that, if authenticationToken is NULL why I don't see NULL AUTHTOKEN on the log.

I get this error the second time I run that method, the first time, I don't get any error. This is my log:

???????????? (null)
NULL AUTHTOKEN

By the way:

NSString* authenticationToken;

Any advice?

Maybe there is a Memory Leak somewhere...
