Is it possible to send Push Notification from one iPhone Device to another?
If yes, then can you please show me how it can be done?
回答1:
No, you can not send Push Notifications directly between two devices. Push notifications are sent from a dedicated server that you own or have hosted by somebody else.
If you want to trigger a push notification from one phone to another then you need to implement a system where the first phone sends a message to your server which then sends the notification to the other phone.
From a users perspective it will work like they send it directly, but technically it's a bit more complicated.
