Snapchat offers a lot of fun features but it's original purpose was to be able to send private messages and photos that disappear after a they have been viewed. Receiving banner Notifications from Snapchat can defeat the purpose of having a private conversation through the app. Luckily you can disable Notifications for any app on your iOS device by following these steps:
- Open the Settings app on your iPod touch, iPhone or iPad.
- Tap Notifications.
- Scroll down until you see the app you want to block and tap that app's panel.
- Tap the Allow Notifications slider so it is OFF/WHITE.
This will stop any app from sending your banner Notifications to your iOS device.
