Can I release a no longer needed property of an instance of an object without worrying that dealloc will later "over-release" it?

I have an instance of an object "myObject" that has a few UIImage objects as properties. After I access these properties the first time I really don't need them any more.

Can I do a release on the instance's UIImage properties before the instance itself is released, or will this over-release the UIImage properties later when the "myObject" dealloc releases them also?

Any time you release an variable that is still in scope, you should immediately set it to nil. This will avoid the problem you're discussing in -dealloc. The best way to achieve this is to always use accessors. If you use accessors, then calling self.foo=nil will take care of everything for you.
