Can a variable bu used 2nd time after releasing it?
- by Jakub
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!
