Why can't I see the content when the other party sends a text message on an Apple phone?

When using the iphone, the received SMS will be displayed on the home page, which will be inconvenient, especially when you don't want others to see it. Here are the steps for Apple's mobile phone to make text messages not display content:

First turn on the iphone and click "Settings".

Then click "Notify"

Secondly, click "information"

Then close the display preview.

Finally, the setting was successful.
