iOS Question Download file and decompress

[GiulioVale]

Hi Erel,
any suggestion about b4a to b4i for this line of code

    Log("Job completed: " & Job.Success)
    Dim Inizio As InputStream
    Dim Out As OutputStream
    Dim CS As CompressedStreams
  
    lblDownloadProgress1.Text ="Decompressione in corso..."   
    DoEvents
    Inizio = CS.WrapInputStream(Job.GetInputStream, "gzip")
    Out =  File.OpenOutput(File.DirRootExternal & "/" & Main.directory_programma, Main.nome_file_indirizzo,False )
    File.Copy2( Inizio,  Out)
    Out.Close
    Job.Release
   
    lblDownloadProgress1.Text ="Decompressione completata"   
    DoEvents

thanks

Something like:

Dim cs As CompressedStreams
Dim data() As Byte = cs.DecompressBytes(Bit.InputStreamToBytes(Job.GetInputStream), "gzip")
Dim In As InputStream
In.InitializeFromBytesArray(data, 0, data.Length)
Dim out As OutputStream = ...
File.Copy2(In, out)

Again Erel,
any suggestion how populate progressview with transfer data ?

btw: B4i is already wonderfull

 

[Erel]

Do you mean during the download? How large are the files?

Yes. Around 60 Mega or more

The method I posted will not work as it will try to read the file into memory.

However if your server is configured correctly, which means that it returns the correct encoding header then the file should be decompressed automatically.

Uhm strange your method work

Dim CS As CompressedStreams
  Log("Decompressione in corso...")
  
   Dim data() As Byte = CS.DecompressBytes(Bit.InputStreamToBytes(j.GetInputStream), "gzip")
  Dim input As InputStream
  input.InitializeFromBytesArray(data, 0, data.Length)

  Dim output As OutputStream
  output =  File.OpenOutput(File.DirLibrary  & "/" & directory_programma, nome_file_indirizzo,False )
  File.Copy2( input,  output)
  output.Close  
   Log("Decompressione completata")

My file is correctly download and decompress.

Hello all! I'm trying to use inputstream to receive bytes from s socket. I did this in Android using inputstream.BytesAvailable but this property seems to be absent from the IOS implementation. What can be used instead?
