I have a class with one simple method that accesses an IBOutlet (an
NSPanel to simply either order it to the back or to the front).
However, after the first time in which I access the method in the
class, the IBOutlets are released and then if, at a later time, I
wish to access this method again, it does nothing since, I assume,
the IBOutlet which it is accessing has dealloced. How do I prevent
this?
Your question is incomprehensible to me.
Class methods can't access instance variables and all IBOutlets are
instance variables. Do you perhaps mean you have an instance method
that "accesses" an IBOutlet ?
You will have to show us some code to get any kind of sensible
answer. For example, what on earth do you mean by "access" a
method ? Do you mean send a message to an object ? Do you mean edit
the method in a text editor ?
Nothing happens spontaneously in Objective-C. What do you mean
IBOutlets are released ? First of all IBOutlets are pointers to
objects. Perhaps you mean that the object referenced by the outlet
is released ? What makes you think that ? Did you write code to
send a release or autorelease message to the object ? If the object
which the IBOutlet is "accessing" was truly deallocated, and you
"access" is (by sending a message) your application will most likely
either crash or very strange things will happen.
The normal way to prevent an object from being deallocated is to
retain the object. Does just that statement answer your question ?
Did you perhaps configure you panel in Interface Builder so that it
is released when closed ? Are you closing the panel or just ordering
it front and back like you claim ?
