Eli,
What is the easiest way to instiante an object (for example an
NSmutableString)
such that is is visible to ALL functions and methods in a program
Make it a global variable, just like C.
How would I then destroy this object at
the end of my program?
Usually, you just don't. It'll get destroyed when your application
exits along with the rest of your memory space.
How generrally does scope work in objective C? In regular C, if a
variable is
defined in a function, it is only visible in that function. In
objective C,
are objects created (say in a method of some object) global in scope?
Objective-C scoping is generally the same as C, because Objective-C
*is* C with a Smalltalk-style object model.
Basically I have application data that I want accessibly to all of my
window
controller objects and custom handling objects, etc. What is the
safest way to
do this?
Probably global variables unless you are using threads, in which case
you need extra safeguards.
I suggest reading Apple's online documentation on the Objective-C
language. Most of your language questions would be answered therein.
David.
