Question

I would like to know how to release a strong property. I would like to clarify why I intend to do this. I own an object via this property declaration:

@interface MyClass : NSObject {
  __strong MyObject *myHeavyObject;
}
@end

I create this object in some method, I use it in another, so on and so forth.

- (void)someMethod {
  myHeavyObject = [[MyObject alloc] init];
  ...
}

- (void)someOtherMethod {
  id response = [myHeavyObject getResponse];
}

At some point however, i KNOW i no longer need it, and since it is heavy, I would like to get rid of it:

- (void)someCallDidFinish {
  //i no longer need myHeavyObject...how do I get rid of it?
}

I don’t want to wait till dealloc since that could be a long time. I know I don’t use this object any more, so how can I make it go away? How is this supported in the ARC paradigm? Is this something reasonable to ask for?

Just set it to nil. The old value will be released when a new one is set.
