在应用中推送通知

Question

I have successfully set up a MySQL+PHP push notification server and everything is working fine and dandy, except for one thing. If the user happens to be in the app, they do not get the push notification, which is kind of annoying. Is there a way I can modify this so it will show the push notification in Notification Center or something?

Thanks for the help in advance!

Answer 1

When app is running below method is called

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

You cannot add anything to notification center using SDK. If notification is received when app is not running iOS add it in the notification center. You can show alert yourself in above method like this

if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive)
{
   //show alert
}

Answer 2

If your user is in the app your app will get a message to the app delegate. See

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

in the Apple Documentation

You cant put a notification in notification center while the app is open. Notification center is designed to capture notifications that happen while the app is not active. However the call to the app delegate is useful as you can display the notification to the user in any way you want to, including building your own notification center style animation if thats what you want.
