Hello, all ...

Imagine this:

static NSMutableDictionary *lookup = [NSMutableDictionary new];

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

[lookup removeAllObjects];

is probably your best choice.

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,

Maybe marginally; that release is going to cause a -release to be sent to every object in the dictionary anyway, although Apple's implementation is likely optimized.


My suggestion above prevents another object creation.

but since it was declared as static, which is safer?

I don't think safety matters either way, in this case.
