How does Apple 4s get the weather on the desktop?

If you click on the weather application, every apple should have one.

After clicking, a weather page should pop up with an exclamation point in the lower right corner. You can click to enter the setting interface and enter your place, which seems to be all right at the urban level. You can enter a search, and then choose the weather in your location.

After setting it, you can directly click off the original weather in Beijing and Shanghai, and just leave one.
