when/where should properties be released once the objects is pushed for display?

Question

Hi,

I've defined a view controller with an array as one of its properties, and set the array with an allocated and autoreleased array. After I push the view for display I release it.

By watching the leaks tool I see that every time that I pop the view I suffer from leakage. I tried to release the properties explicitly, immediately after the push but the app crashes.

looking forward for your suggestions.

The leak is probably because of the array property is set to retain, like so:

@property (nonatomic, retain) NSArray *yourArray;

Your autorelease object is retained on assignment to the yourArray property. Since it is retained, you have to release it in the controller's dealloc method:

- (void) dealloc {
   [yourArray release], yourArray = nil;
   [super dealloc];
}

HTH.
