I have created Edit Fields in the interface, but I have no idea how to store values from the created EditFields.
Example: when I enter n as 2 and press button, It creates 2 edit fields, code is as follows.
% Button pushed function: Button
function ButtonPushed(app, event)
n=app.nEditField.Value;
for i = 1:n
app.EditFields=uieditfield(app.UIFigure,'text','Position',[100 350-20*i 150 20],'Placeholder',sprintf('Enter number '));
end
end
After entering the values in editfields and pushing the button2, The values must be store in a cell.

I don't suggest you create them on the fly. I suggest you just create them all with known names in advance. Just set their visible property to hidden/off. Then (in the button callback if you wish) you can use a switch or if to make all visible up until the nth box and invisible after that. Then since you know their names, you can easily get the contents just like you did for n.
Attach your .mlapp file if you need more help, after you read this:

One problem is that you aren't storing the handles to the edit fields as separate entities. As you loop, "app.EditFields" is being overwritten, so you only have access to the latest one. But in general, to access the value, you can reference the value:
app.EditFields.Value
