Answer 1

There are some good discussions on this topic here:

Retain/release pattern for UIPopoverController, UIActionSheet, and modal view controllers?

UIPopoverController and memory management

The gist of it is you need to:

• assign your autoreleased popover to a retain property
• set the property to nil in your view's dealloc
• as well as setting it to nil in the popoverControllerDidDismissPopover.

Answer 2

think autorelease is incorrect, here is a tutorial
