<p>I would like to show a set of consecutive numbers in a UIPickerView component but have it wrap around like the seconds component of the Clock->Timer application. The only behavior I can enable looks like the hours component of the Timer application, where you can scroll in only one direction.</p>

I found my answer here:

When it asks for the title of a row, give it:
Code:
```
```
return [rows objectAtIndex:(row % [rows count])];
```
```
When it says the user didSelectRow:inComponent:, use something like this:
Code:
```
```
//we want the selection to always be in the SECOND set (so that it looks like it has stuff before and after)
if (row < [rows count] || row >= (2 * [rows count]) ) {
    row = row % [rows count];
    row += [rows count];
    [pickerView selectRow:row inComponent:component animated:NO];
}
```
```
It appears that the UIPickerView does not support wrapping around natively, but you can fool it by inserting more sets of data to be displayed and when the picker stops, centering the component to the middle of the data set.
