lets say I have an array of object instances [Foo] the is filled in a manner similar to this
var temp = myObject(parameters)
foo.append(temp)
then elsewhere I create a stack (yeah I know its just another array)… but this is a FILO message queue to process selected objects in order
myStack.append(foo[3])
Now FOO has pointers to all the active instances of “myObject” and myStack has a pointer to instance #3 (ok #4 as it is zero based)
here is the question, and I think I know the answer, just want to be sure
foo.remove(at:3)
a) does it set myStack[0] to NIL?
b) or does the instance live on due to ARC???
if “b” then would I have to do this instead
foo[3]=nil
foo.remove(at:3)
there is a timer that looks at mystack and an processes the top entry. But if it has been removed from foo, then I need that entry to be nil so I can skip it
