combine two functions into a UITableViewCell: selection and information

I'm using a UITableView to present options to the user. The user can select one option by clicking on one of the cells. The concept is similar to the Radio开发者_JAVA百科 input in html forms.

I'm looking for some ideas on how to combine two functions into a UITableViewCell. I've taken care of the selection function. I would like to also let the user get information on a particular UITableViewCell. The information is text that will not fit into a subtitle on the UITableViewCell.

Create mirror arrays, one with info for the selection, and one with the other information; then on selection, insert the other info into the first array in the appropriate position and display

Or

Create a footer under the tableView and display the info whenever a cell is selected.
