I want to change the Color of the "Barrel" inside the picker with a gradient from red to blue (Temperature: hot to cold).
I could draw the gradient piece by piece with -(UIView*)pickerView:(UIPickerView*)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView*)view
but then, what's about the space over the first and under the last row?
Is there a better way to do this? Or is it possible to manipulate the "Barrel" directly?
