iOS Select TableViewCell TextField when not visible

[donaghy]

I have a fairly basic data entry form. It's a tableview with typical sections and rows with a custom tableviewcell that contains a textfield. I have a next and previous button to move between table cells however if a table cells is disabled i want to skip it and move to the next enabled table cell. Though on some occassions the next enabled cell will not be visible and not in memory. How can i select a table cell in this instance?
