iOS >>本地通知>>如何将本地通知连接到特定对象？

In my app I keep an array of data objects; upon certain actions, a Data Object is creating a Local Notification. I wish to have the Local Notification be able to recognise the Object that created it, so when the user opens the notification - whether it's from a UIAlertView that pops if the Notification is fired when the app is active, or whether it's triggered by the Notification view that pops when the app is in the background - I can open a screen with the specific Object Data presented.In my app I keep an array of data objects; upon
