Re: NSString subclass responsibility

[Fred Kiefer]

I was hoping for somebody else to answer this. There are different subclasses 
that provide the implementation for NSString, most importantly GSString. Within 
an Obj-C application NSString in itself is never instantiated. The problem you 
are facing is that your non Obj-C code may try to instantiate an NSString 
object. Just stick to the [[NSString alloc] initXXXX] pattern or get your 
strings from one of the factory methods.

Hope this helps,
Fred
