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