I'm using a UIPickerview to 'collect ' several parameters using two components. Once the parameter type (component0) and a value (component1) are reached the user can select them by hitting an accept Button and moving on to the next parameter. I want to change the color of a UIPickerview row when the values have been selected and I want to do this via an IBAction connected to the Button. I can get the row to change color through an UIColor colorWithRed green blue etc but I don't quite know how to wrap it up in the IBAction. Can someone please advise me?
