iOS Question AirPlaneMode check sometimes wrong

[mcorbeel]

I use this piece of code to check airplane mode on an iPhone. Some users complain that it gives "True" even when they are on a network. Is there something wrong?

Sub Device_AirPlaneMode() As Boolean
    Dim R As Boolean = False
   
    Dim myLan As ServerSocket 'ignore
    Dim sDeviceIP As String = myLan.GetMyWifiIP
    If sDeviceIP = "127.0.0.1" Then
        R = True
    End If
      
    Return r
End Sub

Your code looks correct. In most cases it is better not to make any check and just try to connect to the desired destination. If it works it works and if not you show a message that there is no connection.

Maybe so.
Is my code correct for 4G too? Is should give false when not connected to wifi but connected to 4G (not airplane mode).

You are right. The code is not correct. GetMyWifiIp returns the wifi ip address. It doesn't check the cellular network status.

okay, will follow your advice and check on each connection
