how to make iPhone app asks to register device for push notification multiple times

Question

I have used the following code to register my app to receive push notification, and I got the alert that asks me to register for push notification and I accidentally press cancel. Now I want to have the alert again so I can fire the delegate method in order to get the device token. But I don't get this alert any more and every time I open the settings I found that the notification is turned off for the app. I tried to delete the app from device, change app version, delete testing profile ,clean the target even I reset all the iPhone settings, but still was not able to solve this.I would very much appreciate any help, thanks

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge | 
     UIRemoteNotificationTypeAlert | 
     UIRemoteNotificationTypeSound];  

Answer 1

Theres a notification option in the settings. Check out your application and turn on the notification from there.

I have learned somewhere that iOs 4 has this bug that it wont ask again even if youremove and reinstall the application.

Try Settings->Notifications-> your app-> Turn it on.

Hope it helps. Thanks
