Read the Memory Management Guide. All of it. If you don't understand something stop until you do.
You are assigning an autoreleased value to db1 so you cannot expect that to exist at some undefined point in the future.

That is the reason. If you don't know what that means you need to go back to basics. Did you read the document I linked to? Have you read the Objective-C guide on the developer site? If you don't know what that means you don't have the most basic knowledge you need.
