I'm currently doing the following to clear out an NSMutableDictionary
[myDictionary release];
myDictionary = [[NSMutableDictionary alloc] init];
The release line doesn't actually release any objects in the dictionary. I can still see all of them on the next line. It isn't until the alloc line is executed that the dictionary is zeroed out. Is there a better way to do it?

The clear() method removes all the elements from a dictionary.
Python dictionary clear() method is used to remove all elements from the dictionary. When you have a dictionary with too many elements, deleting all elements of the dictionary one after another is a very time taken process, so use clear() method to delete all elements at once rather than deleting elements one by one.
I can't test it at the moment, but have you tried the removeAllObjects method of NSMutableDictionary?
