I am using the app designer to create an app with quite a lot of properties here is a smal sample:

        MemValue_1_1                   matlab.ui.control.EditField
        MemValue_1_2                   matlab.ui.control.EditField
        MemValue_1_3                   matlab.ui.control.EditField
        MemValue_1_4                   matlab.ui.control.EditField
        MemValue_1_5                   matlab.ui.control.EditField
        MemValue_1_6                   matlab.ui.control.EditField
        MemValue_1_7                   matlab.ui.control.EditField
        MemValue_1_8                   matlab.ui.control.EditField
        MemValue_1_9                   matlab.ui.control.EditField
        MemValue_1_10                  matlab.ui.control.EditField
        MemValue_1_11                  matlab.ui.control.EditField
        MemValue_1_12                  matlab.ui.control.EditField
        MemValue_1_13                  matlab.ui.control.EditField
        MemValue_1_14                  matlab.ui.control.EditField
        MemValue_1_15                  matlab.ui.control.EditField
        MemValue_1_16                  matlab.ui.control.EditField
        MemValue_1_17                  matlab.ui.control.EditField
        MemValue_1_18                  matlab.ui.control.EditField

        MemValue_1_41                  matlab.ui.control.EditField

        MemValue_1_47                  matlab.ui.control.EditField
        MemValue_1_48                  matlab.ui.control.EditField
        MemValue_1_49                  matlab.ui.control.EditField
        MemValue_1_50                  matlab.ui.control.EditField
        MemValue_1_51                  matlab.ui.control.EditField
        MemValue_1_52                  matlab.ui.control.EditField
        MemValue_1_53                  matlab.ui.control.EditField
        MemValue_1_54                  matlab.ui.control.EditField
        MemValue_1_55                  matlab.ui.control.EditField
        MemValue_1_56                  matlab.ui.control.EditField
        MemValue_1_57                  matlab.ui.control.EditField
        MemValue_1_58                  matlab.ui.control.EditField
        MemValue_1_59                  matlab.ui.control.EditField
        MemValue_1_60                  matlab.ui.control.EditField
        MemValue_1_61                  matlab.ui.control.EditField
        MemValue_1_62                  matlab.ui.control.EditField
        MemValue_1_63                  matlab.ui.control.EditField
        MemValue_1_64                  matlab.ui.control.EditField

It should be very obvious that this is bad code and I would like to use an array of MemValues but sadly due to the restrictions of the app designer I can not do that since I would need to modify the code that is not editable in the app designer. Is there any way to solve this issue?

Btw: I know that I can export to .m file where I could do that but I can not reconvert that to the .mlapp file

在 MATLAB Online 中打开

One thing you can do is construct the array of components in the app's startupFcn, e.g.:

N = 64;
app.MemValue = gobjects(1,N);
for ii = 1:N
    app.MemValue(ii) = app.(sprintf('MemValue_1_%d',ii));
end

A new app property (here it's called 'MemValue') would also have to be added.

Not currently in R2024a or any previous release.

"the fundamental problem is, that you can not edit any code inside the createComponents in the AppDesigner CodeView"

@Moritz: I thought the problem was that you "would like to use an array of MemValues". You can do that. Let App Designer create the components one at a time as it does (using properties MemValue_1_1, MemValue_1_2, etc.), and in your startupFcn construct an array of those components, as shown in my answer.
