I've created a table from a data.plist and was trying to figure out how to add a disclosure button at the second level-to-third level table. It would be used to add a UIView "credits" to the student artists who made the picture. However, I need to make sure that the name can change as the table will house different files from different students. So for example, cases 1-3 would all be Aubrey's work, and cases 4-6 would be Josh's, etc.
Any help would be great.

If you want to indicate a disclosure in the cell you can make use of the property accessoryType
.
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
Which can have any of these
typedef enum {
UITableViewCellAccessoryNone, // don't show any accessory view
UITableViewCellAccessoryDisclosureIndicator, // regular chevron. doesn't track
UITableViewCellAccessoryDetailDisclosureButton, // blue button w/ chevron. tracks
UITableViewCellAccessoryCheckmark // checkmark. doesn't track
} UITableViewCellAccessoryType;
