How does Apple's mobile phone display the weather forecast on the screen?

The weather in Apple's mobile phone can't be displayed normally. How to deal with:

The "Weather" app needs to be networked, and the positioning function should be turned on. If the weather information cannot be displayed normally, please follow the following steps and try again after each step.

1. Check the network: Make sure that the iPhone can access the Internet using "cellular data network" or "wireless local area network" (Wi-Fi);

2. Set the network access authority: upgrade to the device above iOS 10 of Bank of Chinese mainland, enter Settings-Cellular Data Network-Applications Using WLAN and Cellular Mobile, click the weather to view WLAN and cellular mobile data. This setting does not apply to China banks that do not sell in Chinese mainland;

3. Turn on the location function: then enter Settings-Privacy-Location Service, tap the weather, and check "Always" in "Access allowed location information";

4. Restore all settings: If conditions permit, go to Settings-General-Restore and click Restore all settings. If the display is still not normal after the above problems are eliminated, it may be a server problem of the meteorological data provider. I suggest you try again later.
