Answer 1

Your subtitle property is declared with a copy attribute, which means you are responsible for releasing it. The following change to your dealloc method should do the trick:

-(void)dealloc{
    [subtitle release];
    [title release];
    [super dealloc];
}

Edit: To elaborate: Cocoa's memory management rules state that you must release any memory that you alloc, retain or copy. In the case of synthesized properties, this means that you must include the appropriate release messages in your -dealloc method. See my own question on this topic for more details.

In the sample code that you provided, the following line:

ann.subtitle = [[xmlParameter objectAtIndex:i]objectAtIndex:1];

Creates a copy of the indicated object. When you later call [ann release], that copied object will be leaked unless you explicitly release it.
