要取消ARC下自定义UIView的dealloc中的出口？

Question

Usually in a UIViewController subclass, I nil out all outlets in viewDidUnload. But in my custom UIView, should I nil out those outlets (defined in my custom UIView) in dealloc instead? Does ARC perform these actions automatically?

Answer 1

No, still do it in viewDidUnload to get them out of memory as fast as possible.

ARC means you don't need to do it anywhere but it's still a bit more efficient if you do.

Though you don't ever need to nil properties in deadlock when using arc in any of your classes.
