How does Apple use real-time weather as wallpaper?

You can't set the weather forecast on the iPhone desktop.

Apple's mobile phone notification bar weather forecast settings are as follows:

1, enter the settings.

2. Slide the options bar up to find the privacy option.

3. Click to enter and open the location service.

4. Find the weather option to see if the location service is turned off. If it is, it needs to be turned on.

5. Enter the weather and refresh it.

6. At this point, slide down the notification bar and you can see that there is a weather notification.
