Hello, all ...
Imagine this:
static NSMutableDictionary *lookup = [NSMutableDictionary new];

If I call
[lookup release];
lookup = [NSMutableDictionary new];

each object in the dictionary, but since it was declared as static,
which is safer?
As long as you are not retaining the objects referenced in the
dictionary elsewhere, then when the dictionary is deallocated, all of
its' referenced objects will be released. Whether the dictionary was
declared static or not does not affect its' contents.
I don't know of any reason to ever iterate over a dictionary removing
its' elements before you release it unless you are intending on saving
copies of those elements elsewhere.
