iOS Question Sample code for sending data from iOS device to server (UTF8)

[dclarkchem]

Have successfully created an app with B4A, but wondering if there is sample code to do this with B4i. Here is part of what we've done with B4A:

Sub Socket1_Connected(Connected As Boolean)As Boolean
    If Connected = True Then
        ToastMessageShow("Connected",True)
        lblMsg.Text="Connected!"
        Main.AStreams.Initialize(Main.Socket1.InputStream,Main.Socket1.OutputStream,"Astreams")
    Else
        ToastMessageShow("Server not available",True)
        lblMsg.Text="Server not available"
        btnConnect.Text = "Connect"
    End If
    btnConnect.Enabled = True
End Sub
Sub AStreams_NewData (Buffer() As Byte)
    Dim msg As String
    Dim cMsg As String
    Dim unsignedi As Int
    Dim signedb As Byte
 
    msg = BytesToString(Buffer, 0, Buffer.Length, "ASCII")
    Log(msg)
    For i = 0 To msg.Length -1
        signedb = Buffer(i)
        unsignedi = Bit.AND(0xff, signedb)
        cMsg = cMsg & Chr(unsignedi)
    Next
    Log(cMsg)
    lblMsg.Text = x & " / " & msg.Length & " - " & msg
 
End Sub
Sub SendData(msg As String)
    Dim Buffer() As Byte
 
    Buffer = msg.GetBytes("UTF8")
    Main.AStreams.Write(Buffer)
    Main.AStreams.Write(Array As Byte(254))
 
End Sub

Would appreciate any help, before I spend 3 weeks and then figure out that it can't be done with B4i.[/code]

You can use the exact same code in B4i.

Network example: [B4X] Network + AsyncStreams + B4XSerializator

Thanks for that link. After spending a couple of days trying to get the serializator to properly work with our project(s), we gave up in frustration. We were about to abandon all hope, but decided to take Erel at his word ("the code works for both B4A and B4i").

We stripped down our working B4A program (part of it is shown above) to the bare essentials and verified that it still worked. We tried to write the B4i equivalent. There are definitely structural changes that had to be made, but we got it working this morning ! ! !

OK, we're only half way to first base, but at least we're in the game again.
