Deleting scrollView and textField's

hayful59 · May 6, 2019, 4:50am

Hello, Im drawn to the screen a scrollView that Im using for the instruction but I cant seem to remove/delete it ive tried using this:

display.remove(scrollView) scrollView = nil;

It doesnt seem to do anything, the same thing happens when I try to remove/delete a textField. Does anyone know why this keeps happening?

Thanks

We need to see more code. I suspect that your scrollView variable is out of scope in the place you are trying to delete it, but will need to see what you’re doing to confirm.

declare infoScroll at the top of your module
