Save a TiniFile from application to iOS

I am very new to the iOS platform. I am trying to save an INI file for my application. The problem is that I can't get a path with write permission.

Here is my code:

  ini := TIniFile.Create(GetHomePath + '/user.dat');
  try
    ini.WriteString('data','user',edtuser.Text);
    ini.WriteString('data','descr',edt1.Text);
  finally
    ini.Free;
  end;

I get an exception that the file can't be created. How can I get a writable path using Firemonkey?

Solution

  • Use TPath.GetDocumentsPath (and use TPath.Combine instead of concatenation, to remove the hard-coded /):

    uses
  System.IOUtils;


ini := TIniFile.Create(TPath.Combine(TPath.GetDocumentsPath, 'user.dat'));

    Using TPath.GetDocumentsPath works across all supported platforms (Win32, Win64, OSX, iOS, and Android) transparently, and using TPath.Combine will automatically add the TPath.DirectorySeparatorChar, so you don't have to manually concatenate them.

    If you prefer to do it yourself, though:

    var
  IniName: string;
begin
  IniName := TPath.GetDocumentsPath + TPath.DirectorySeparatorChar + 'user.dat';
  Ini := TIniFile.Create(IniName);
  try
    // Rest of code
  finally
    Ini.Free;
  end;
end;
