ShowMessage on iOS???

Hi,

This code works on the Android, but not in the iOSSimulator.

On the Android I get the pop-up and I click OK and the app exits. Which is what i want if the database is the wrong version.

But on iOS all I get is a blank screen, no error, nothing.

The database has a Version table with one record with one integer field containing the version number.

procedure TChirpDB.FDChirpDBAfterConnect(Sender: TObject);
begin
  VersionDS.Active := True;
  if (VersionDS.Fields[0].AsInteger = 1) then
  begin
    ShowMessage('Wrong Database Version, please reinstall.');
    Halt;
  end;
  VersionDS.Active := False;
end;


The SQL in the TFDQuery is:

     select id from Version


The database is SQLite.

I tried changing the comparison to <> so it would not error and the application came up with no problem so I think the problem is in the If Then clause.

Hello,

Yes this is a known bug that the iosSimulator wont show message alerts, this should be fixed in the Delphi XE5 Update 2 release,

Im sorry i cannot help any further.

Oh,

OK, as long as it works correctly on the real device then that's ok.

I've held off with update 2 since I saw several posts that it broke mobile apps and I didn't see any posts that it was ever fixed.

Hi,

Yes, the update MAY break a few things, however once produced on a Device all should work seamlessly.

Glad i could be of assistance , and good luck with your App !,

Conner.
