That one is already stored by your NSApplication object:

[NSApp delegate]

NSApp is a predeclared global variable that holds the current  
NSApplication instance.

Hi again!

I feel like I'm getting there. Though any help is still greatly appreciated!

It does work! I create the "secondSubObject" inside my
"secondMainObject" and after that I set the property
"secondMainObject" in "secondSubObject" to secondMainObject's "self".

Only it is available after the object is initialized. I want to access
the property already during initialization.

Sorry for spamming the list. Please tell me if I should stop. :-)

Or do I have to populate the variable once I created the object? I
created the accessor in "secondSubObject" as you said and tried (in
"secondMainObject")

secondSubObject.secondMainObject = self;

But it doesn't seem to work.

Hmpf!

OK I did that. But as far as I can tell I now have an empty variable
named "secondMainObject" located in "secondSubObject". How do I store
the reference to "secondMainObject" in the variable?

And how do I do this with my main application delegate? I want to call
it from wherever I am.

Thanks again for your help!! I can't stress this enough!

Use accessors. In secondSubObject, create an @property(assign)  
SecondMainObject *secondMainObject; so that you can call methods in  
secondMainObjct from secondSubObject.


Note that it's important that you assign instead of retain in this  
instance, or else you'll create a retention loop memory leak unless  
you're using GC.



And how can I alter a variable in "firstMainObject"?



Again, use accessors so that objects can communicate with other objects.

Re: Newbie: Referencing Objects (second try)

[john fogg]

Hi again! And thank you for your kind help!!

Let me rephrase my question. I create two objects: "fistMainObject"
and "secondMainObject". Inside the second I create another object
called "secondSubObject".

When I'm inside "secondSubObject" how can I alter a variable in
"secondMainObject"?

And how can I alter a variable in "firstMainObject"?

Thanks again!
