Question

I store an NSMutableDictionary in a plist file.
and when I read it into a property of my object, I need to be able to edit it.
my properties pointer is NSMutableDictionary only,
However the object which gets generated from the plist is NSDictionary.

and Now I want to be able to add more key value pairs or delete few and save again.
Which I cant as it is an immutable object now.

the object gets created in init of my Model.

How should I go about it ?

Answer 1

This should do what you need:

NSDictionary * dict = [NSDictionary dictionaryWithContentsOfFile: <myfilename>];
NSMutableDictionary * mutableDict = [[dict mutableCopy] autorelease];
