How to save a figure in user defined path in GUI?

Hello All, I my GUI, I take a path from user to save the results as follows:

% --- Executes on button press in pushbutton3.
function pushbutton3_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton3 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
%is not a number then input will be empty
input = get(hObject,'String');
%checks to see if input is empty. if so, default input1_editText to zero
if(isempty(input))
  h=msgbox('Please select the output folder');
end
guidata(hObject, handles);

S4.selected_dir = uigetdir();
set(handles.edit27, 'String', S4.selected_dir)
set(handles.pushbutton3, 'UserData', S4);

Now in another function the calculation works and figures are generated. Now I want to save these plots in the path given by the user. so I have this code:

saveDirectory = [pwd 'S4.selected_dir\Case_' num2str(ii)];
    % check if folder exists, if not, then create
    checkExistence = exist(saveDirectory, 'dir');
    if ~(checkExistence == 7)
        mkdir(saveDirectory);
    end
    saveas(gcf,[saveDirectory '\1.png']);

Which is not correct as nothing is being saved there. I am not sure about the line:

saveDirectory = [pwd 'S4.selected_dir\Case_' num2str(ii)];

Can anyone suggest me how to save it on the path chosen by the user?

saveDirectory = S4.selected_dir;

No quotation marks, no concatenation, no pwd.

The output of uigetdir() is already fully qualified.

but I want to save them in user defined folder with subfolder names Case_1, Case_2 etc.
