How release subviews?

I created a new view1 in view, and then how should we deal with view1 after addsubview?

CustomViewController * customViewController = [[CustomViewController alloc] initWithNibName: @ "CustomViewController"];
[Self.view addsubview: customViewController.view];
[CustomViewController release];

Above: if I release customViewController self.view will be displayed above the top toolbar is only one jump a customViewController.view display. But if I do not release it, it will be a memory leak. How to handle this.
I Useful [[[CustomViewController alloc] initWithNibName] autorelease] behind release effect is the same.

But your [customViewController] is local, you need time to create either create a class variable, or saved when created, keep [removeFromSuperview] when used.
