2 UIPicker and 1 UILabel
Connect Datasource and delegate of both picker to file owner.
NOTE:-
Sorry for naming convention. You can achieve this multi picker by using one pickerView and divide it in number of columns.
In numberOfComponentsInPickerView return how many columns you want in one pickerView.
