How do Apple phones share their geographical location?

Take the iPhone 7 mobile phone as an example, and the specific methods are as follows:

First, click the information item on the desktop of iPhone 7.

Second, after entering, find out the short message that needs to share the location with this friend, and click "Details" in the upper right corner.

3. After entering the detailed information, find "* * * Enjoy My Location" and click Enter.

Fourth, I shared my geographical position after I went in.
