Also, I'm not entirely happy with this solution because it's tied to an object when it shouldn't need to be. So your -doItLater: method only works in the class you declare it in, and it has the side effect of keeping the receiver alive until the block runs, even if it doesn't need to be (i.e. if the block doesn't refer to 'self' at all.) Someone else had a solution that involved adding a category method to NSObject to invoke the block, but that seems a bit kludgy too. —Jens
