MFMailComposeViewController and MFMessageComposeViewController Access Violation?

[Benjamin garcia]

hello, I'm developing an ios app using DPF.IOS but when i try to use MFMailComposeViewController I get an Access Violation error, can you help me please ?
my code :

procedure SendSMS.TestProcessAnswerSMSSend;
{$IFDEF IOS}
var
  lo_controller: MFMailComposeViewController;
  lo_nsarray : NSArray;
  lo_pointer : Pointer;
begin
  if lo_controller.canSendMail then // Access Violation here
  begin
    lo_pointer := Pointer(nil);
    lo_nsarray.arrayByAddingObject(lo_pointer);
    lo_controller.setSubject(StrToNSString('SUJET GENIAL'));
    lo_controller.setMessageBody(StrToNSString('Un Message'), false);
    lo_controller.setToRecipients(lo_nsarray);
    lo_controller.setMailComposeDelegate(FParent);

    FParent.mailComposeController(lo_controller, 0, nil);
  end
  else
  begin
    Log('Sorry' + #10#13 + 'You cant send Message '#10#13 +
    '1) Your Device not support Message Compose' + #10#13 +
    '2) Text Messaging not available');
  end;
end;
{$ENDIF}

I think my MFMailComposeViewController variable (lo_controller) isn't initialized but i don't know how to do this..
Thanks advance.

I think you can use the DPF.iOS.MFMessageCompose class. It uses the MFMailComposeViewController.
Maybe you can look at the DPF.iOS.MFMessageCompose source and modify it to suit your needs.
