Hello, all ...

Imagine this:

static NSMutableDictionary *lookup = [NSMutableDictionary new];

... now imagine a situation where I need to clear that dictionary. If I call

[lookup release];
lookup = [NSMutableDictionary new];

... it will obviously be faster than coding a for loop and removing 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.
