Reason one, mobile phone is not connected network
1. To show the weather must be able to access the Internet Oh, if not the Internet weather is certainly not to show, whether it is 2g/or WiFi and so on.
2. So if you can't show your network status,
reason two, positioning service
1. If the network determines that there is no problem, see if the weather location is open.
2. In iOS8 "Settings"-"privacy"-"Location Services"-"Location Services"-"weather"-"always" access, as shown in the figure
reason three, the Notification center setting is not normal
1. The notification center is divided into several sections, the weather information is included in its "Today View", so here needs to check the notification Center settings. When you pull up the notification center, click the Edit button at the bottom, as shown
2. If we "Today view" is in "Do not include" click the + button, as shown in the picture
3. Then you can add the "Today View"
Of course we have more options, and it's very simple to use a third party weather app.
