How to invoke “Turn Off Airplane Mode” notification

Question

In many applications, such as the Mail app, if the device is in airplane mode a notification will pop up that says \"Turn Off Airplane Mode or Use Wi-Fi to Access Data.\"

Answer 1

If you want the standard Turn Off Airplane Mode or Use Wi-Fi to Access Data [settings | ok]

1. Add a new property in your info.plist by clicking the + sign at the top.
2. The new property is called UIRequiresPersistentWiFi (this is similar to postings above, but needs to be exact otherwise it doesn't register)
3. Change type from String to Boolean
4. Change value from NO to YES
5. Clean and rebuild your app

Answer 2

Take a look at this. Apparently, Airport control was moved by Apple into a separate framework

It seems there is no standard way to notify the user to turn airplane mode back on. As you mentioned, this obviously isn't very elegant, so I assume apple deleted this feature.

Answer 3

I test in my app. I find it changed. "UIRequiresPersistentWifi" => "Application uses Wi-Fi". I hope it will help somebody.

Answer 4

You could use the apple's reachablity framework when you app launches to check for network connectivity. Check this out

I have a wrapper class for reachbiltiy APIs to make it simpler to use. (ASIHTTPRequest has one as well).

see the GPReachablity class for checking for connectivity. As far as a dialog prompt, not sure there is a way to push to the settings app. Any questions let me know.

Answer 5

If you add the UIRequiresPersistentWifi key to your Info.plist and set it to YES, then if you're in Airplane mode, you'll get the standard "Turn Off Airplane Mode..." popup on launch.
