1) How do I make a module (sub/function library) in ObjC?
It's not clear (to me at least) from your examples what you're trying
to do here. Do you want group methods in a separate class? Just make
a new set of .h and .m files, add them to the project (using File-
>New File->Objective-C Class in Xcode will do these two steps for
you), and #import the new .h file at the head of the class you'll
actually be using it in. If you want to make a library that you can
dynamically link and reuse, read up on Frameworks:

In fact, you might want to read, generally, about adding behavior to
a Cocoa program:

2) What's the default encoding of an NSString literal? I'm guessing
UTF8.
This one was an easy find on Google, by the way. You might want to
try STFW.
Anyway, http://tinyurl.com/gu2lh says that:
@"string" Defines a constant NSString object in the current
module and initializes the object with the specified 7-bit
ASCII-encoded string.
See also: @encode() and +[NSString stringWithUTF8String:]
And how do I append (concatenate) a character (double-quote - ASCII
value of 34) to an NSString?
For most purposes, I would think you'd be able to do:
myString = [myString stringByAppendingString:@"\""];
Is there a reason this won't work for you?
