Memory: object not release after view controller dismiss, with ARC

Question

I have 2 view controller,

FirstViewController - > SecondViewController via

[self presentViewController:SVC animated:YES completion:nil];

on SecondViewContrller when I do

[self dismissViewControllerAnimated:YES completion:nil];

My question is, Why is the objects not release on secondViewController after I dismiss this viewcontroller. As you can see on the graph It didn't go down after dismiss. BTW whats the best way to release/dismiss a ViewController?

[EDIT]

I NSLog a message on dealloc method on every VC, When I start from FVC->SVC->[dismiss SVC]. this is my logs

This can be pretty rough stuff. I had similar issues before. Search your code and see if you have strong or wrong references to objects.

One of my top mistakes (and what I have seen on the internet hundreds of times) are delegate properties. I wrote them like @property (nonatomic, retain) id<protocol>delegate; for quite a long time as I realized that if I do so, the delegated object does not get released. One have to use assign in this case.

Hope that help you...
