I want users to set up pin code - not with the keyboard but with my “stylish” buttons.
To do that I have created the following design:
“* * * *” are to be changed by each tap to my numpad.
1234 is the final 4 digit value actually tied to a parameter. Of course this will not be visible, just for data purposes.
I feel like this can be done by private variables and such but couldn’t figure it out how can I concatenate the 4 digits and only limit users to 4 digits. Any ideas?
