When an iOS app attempts to register for push notifications for the first time, the system pops up a permissions dialog asking the user for permission to receive push notifi
Not possible, since you dont have any control on it whatsoever
No you cant change system in built message.because you dont have any control to it.
One workaround that I have seen involves an app bringing up its own custom dialog explaining why it needs a permission. Then immediately afterwards the app requests the permission, bringing up the system dialog.
This may be suitable for convincing a user to accept the permission request in order to gain access to a feature, or to reject the request with the knowledge that the feature will not be available.
No, this is a system dialog which cannot be customized.
