iPhone: View/Close button click action on push notification message dialog

Could anyone please tell me how to handle push notification dialog's view and close button click from my application? I have gone through this thre开发者_高级运维ad which says to handle it in ViewDidLoad but when I click View button, this method doesn't get invoked. I want to do take user to some particular view on View button click and record the Close button click on my Server. So basically I want to know what happens when this button(s) clicked? I have gone through Apple docs but it nothing say about these actions. Any documentation and/or code sample would be really greatful.

Thanks.

If user clicks view then you can catch that action in didFinishLaunchWithOptions method of AppDelegate class. If user clicks close then, there is no way for application to catch that. If your application didn't get the notification in AppDelegate class, then either you forgot to register your app for push notification or you didn't send push notification properly to APNS.
