UIPickerview - Change Row color in an IBAction

[TrueScot]

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?

What about using the view controller as a delegate and implementing the UIPickerViewDelegate protocol?

Wouldn't implementing pickerView:didSelectRow:inComponent: allow you to determine what has been selected by the user? For disclosure, I've not tried this, but implementation of the callback seems like a good thing to try.

Hi Matt. I've no problem in determining which row in which component has been selected. The user can roll the components indefinitely but there has to be an event when the user chooses to 'keep' the values when the component(s) have stopped. The user has to 'collect' several, different parameters from a broad selection and this is where the button (IBAction) comes in.

Basically, I need to change the row color (in component 0) to indicate to the user that this parameter has already been selected and the user will do this by hitting the button (which in turn will set the color of the row selected). So, the problem is how do I do this in an IBAction (ie. call a method from inside the IBAction?) when I already know the row and component.

Largely a beginner, so take this with a grain of salt, but it doesn't sound like you want another IBAction. It sounds more like you want the class that implements the IBAction to also include IBOutlets mapped to the picker, which should give you programmatic access to the picker and its properties from within the IBAction call.

Sincere apologies if I am off base on this.

"Another IBAction"? "IBOutlets mapped to the picker"? Sorry Matt but I think you may have misunderstood what I'm looking for. I want to fire off a method when I hit the Button (IBAction) - "I don't quite know how to wrap it up in the IBAction". I'm just looking for advice on how best to do this.
