iOS SDK 14.2
There is one combo box on the form.
For the purity of the experiment, the form with the combo box is re-created every time after loading data into it and displaying the drop-down list.
I load objects (JSONObject) into the combobox in the usual way.
for FJSONValue in FJSONArray do
Acb.Items.AddObject( (FJSONValue as TJSONObject).GetValue( ‘name’ ).Value, TObject( FJSONValue.Clone ) );
Also, when cleaning, I delete objects from the combo box.
for index := 0 to Acb.Items.Count – 1 do
if Acb.Items.Objects[index] <> nil then
begin
Acb.Items.Objects[index].DisposeOf;
Acb.Items.Objects[index]:= nil;
end;
Acb.Items.Clear;
On lap 2-3, after loading the content into the combo box, when you call DropDown (programmatically or via the GUI with a tap / click), the application crashes.
I rarely get an error on the TCustomComboBox class in the method
function TCustomComboBox.GetItems: TStrings;
begin
Result := FListBox.Items;
end;
What am I doing wrong? Am I clearing my memory incorrectly? Adding an object incorrectly? Why does it crash when trying to call the dropdown itself?
On Win10 and android works without problems.
