How to display the message "Cellular data is disabled"?

Apple built-in apps display a pop-up message when the user has no cellular or Wi-Fi connection. It looks something like this:

"Cellular data is disabled

Turn on cellular data or use Wi-Fi to access data

[Settings] [OK] "

Clicking the "Settings" button opens the settings panel.

Is this a system popup? How can I use it in my application?

I'm already using UIRequiresPersistentWiFi, but it uses a different type of message that appears when airplane mode is on.

See the Apple Sample for a usage example. It will provide you with all the code you need to determine if you are connected or not online.



You need to enable the app using wifi in the info.plist file. This warning is then displayed when cellular data is disabled and you are not connected to Wi-Fi.
