how can I customize local notifications contains GIF when my app scanning NFC tags and get different data from NFC tags.
Set up local notification when scan NFC tag
Once you have implemented background tag reading as explained at Adding Support for Background Tag Reading, when your app launches, you can create a local notification (Scheduling a notification locally from your app) and then create a Notification Content Extension for Customizing the Appearance of Notifications to implement a custom view to display a GIF image.
