Memory error due to [super dealloc] uiview controller

Question

I have an instance uiviewcontroller, and when I release it, the dealloc method is called.

I have released several objects in the dealloc method of this uiviewcontroller.

If I comment [super dealloc], the application works fine, but if it doesn't work.

I think there is no problem with the releases that I make in this method, but if I do [super dealloc], it crashes.

Can anyone help me with this?

- (void)dealloc {

    [super dealloc];

    self.someProperty = nil;
}

, , setter . [super dealloc] :

- (void)dealloc {

    self.someProperty = nil;

    [super dealloc];

}
