If you know the size

NSLog(@"%.*s", 8, contract);

If contract is a NULL-terminated string

NSLog(@"%s", contract);

or just convert to NSString

NSLog(@"%@", [[[NSString alloc] initWithBytesNoCopy:contract length:contractLen encoding:NSASCIIStringEncoding freeWhenDone:NO] autorelease]);

Try

NSLog(@"%@",[NSString stringWithCString:contract encoding:NSUTF8StringEncoding]);

Basically, you need to make the C string an NSString object.

Please go through Format Specifiers. Try %c instead of %@. Hope this helps
