    copied!<p>To my understanding, the only way to change the message send via a push notification before it gets displayed is using the "localization" mechanism.</p> <p>Have a look at the Apple's documentation about "Localized Formatted Strings": <a href="http://developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html#//apple_ref/doc/uid/TP40008194-CH100-SW21" rel="nofollow">http://developer.apple.com/library/mac/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html#//apple_ref/doc/uid/TP40008194-CH100-SW21</a></p> <p>I'm not really sure this is what you are trying to achieve.</p> <p>In my opinion, if you wan't to display different message/data wether your app is in background or in foreground, you should change the data sent via the push notification.</p> <p>Something like this:</p> <pre><code>{ "aps" : { "alert" : "Message displayed when app is in background" }, "foreground_alert" : "Another message or data used when app is in foreground" } </code></pre> <p>When your app is in background, the content of "alert" will be displayed automatically.</p> <p>When your app is in foreground, you will have to implement <a href="http://developer.apple.com/library/ios/#documentation/uikit/reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UIApplicationDelegate/application%3adidReceiveRemoteNotification%3a" rel="nofollow">application:didReceiveRemoteNotification</a> to catch and handle the incoming notification (and display the content of "foreground_alert" by example)</p>
