Question

when I quit my application, if I receive the message, the Notification Bar shows me the reason, but when I launching the application, it just don’t show on the Notification Bar, did I do something wrong or missing? THanks.

Answer 1

You should show custom UIAlertView from UIApplication’s callback:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo

Updated: to read: Handling Local and Remote Notifications:

Let’s review the possible scenarios when the operating delivers a
local notification or a remote notification for an application.

• The notification is delivered when the application isn’t running in the foreground.

In this case, the system presents the notification, displaying an
alert, badging an icon, perhaps playing a sound.

…

• The notification is delivered when the application is running in the foreground.

The application calls its delegate’s
application:didReceiveRemoteNotification: method (for remote
notifications) or application:didReceiveLocalNotification: method (for
local notifications) and passes in the notification payload or the
local-notification object.
