Hello,

I try to understand the memory management in ObjectiveC and still some things are a misery for me. I've got an instance variable:

    NSMutableArray *postResultsArray;

when a button is clicked in the UI I create new array:

self.postResultsArray = [NSMutableArray array];

then I add some objects to the array and when the whole operation is done I would like to release the array:

[self.postResultsArray release];

(I assume that all the objects stoed in the array will be released along with the array). The problem appears when I click the button again and in the code I want to create the array again with:

self.postResultsArray = [NSMutableArray array];

I get:

[CFArray release]: message sent to deallocated instance 0x3d9e390

Can't I initialize the same instance variable for the second time? or maybe I should not release it? and if so, why?

Thanks!
