iphone - apns to open an application without pop-up

Is there a way to open an application without showing the pop-up notification or is this possible only through iOS Enterprise program with Mobile Device Management feature?

currently I have this whic开发者_StackOverflow社区h shows ok after a pop-up. self.updateos = @"{\"aps\":{\"alert\":{\"action-loc-key\":\"\", \"body\":\"update please\"}},\"acme1\":\"updateos\",\"acme2\":42}";

I tried to find answer from here but couldn't... http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html#//apple_ref/doc/uid/TP40008194-CH100-SW10

I want users to go into my program right after I send a push notification.

Thanks.

You're better off adding buttons to the push notification, or better yet in iOS 5, they can slide it in the lock screen. If a push notification pops up while they're in a different app, I think it would be kind of annoying for the user to be switched to your app, and possibly against the review guidelines as well.
