Disable particular row value in UIPickerView

I am trying to disable particular row in pickerView.

I have an array of strings for pickerView. I am appending values in array1 when user selects particular row.

Answer 1

Option 1: Disabling an element

You can give the title a greyed out style with the method pickerView:attributedTitleForRow:forComponent:

Then you can change to a defaut value when that item is selected using pickerView:didSelectRow:inComponent:

Option 2: Delete the item

The second option would be to just remove the item from the possible options by adjusting your datasource.
