How to Set Apple SMS Reminder

Enter the main interface, click Settings, and click Notification in Settings.

After entering the notification, click the information under "Notification Center".

When you pull down the screen, you can see that the "Show Preview" switch is on, so turn it off.

At this point, return to the main interface. When the screen is locked, you can only see who the sender is when you receive the text message, but you can't see the content of the text message.
