How to make UIPickerView Rotational?

Question

Let I have an array [1,2,3,4,5...] and i want to show it in a UIPickerView in swift. But i would like to be it rotational. For e.g after the value 5 next value will be 1, then 2 and so on. Similarly while showing the selected value 1 the previous value will be 5 & so on. To be exact I would like to have the picker view like following
->1->
| 2 |
| 3 |
| 4 |
| 5 |
| 6 |
<- 7<-
