[xmlvm-users] memory management and return of an object

[Panayotis K. <pan...@pa...>]

I've seen that in the code produced by xmlvm, every time an object is  
returned, this object is at the same moment released.
Thus usually in properties we see something like:

return [[self propertyname] retain];

So, can we say that this is a general rule?
I mean, that in any case, no matter what, when the thin library obj-c  
layer is required to return an object, this object should be *always*  
retained?

Is this valid also for objects like usually retrieved with selectors  
like
[UIFont systemFontOfSize:fontsize]
?

I have made some tests with the last one, and even if I don't retain  
it, there is no segfault (which, ok, this doesn't mean anything).


So what is optimum (concerning memory management) ?

Thank you!
