In places other than dealloc where memory needs to be released (e.g,reassigning pointer to objects), is there a difference in doing autorelease or release of the object in terms of perfomance etc. ? I can see that thememory is released immediately in one case whereas in the other it isslightly delayed. Is there any other difference ? What is the right thing todo ?
autorelease would take slightly longer because in addition to the actual release that is eventually called, there is the overhead of adding the object to the autorelease pool. Except inside really tight loops this would likely not even be noticeable.
Another factor is that if the pool doesn't get drained for a while, your app's working set will be higher than if you had used release. Again, probably a negligible difference except in edge cases.
From a style perspective, I would probably use release, because I think it describes my intention better - I'm saying that I absolutely don't need this object any more.
