ios equivalant of spinner

What are the possible choices to use in B4i as the equivalant of the B4A spinner view? I am converting my B4A app to B4i and am not very familiar with iOS - never had an iPhone before. I searched but could not find an example of a picker view and have looked at the XUIViews.

"B4XComboBox is based on an ActionSheet in B4i."
Under ios there is no way to change the appearance of the elements in the B4XComboBox

Thanks for your reply..Means text color and background color can not be applied?

Aside this, how to add item and clear?

Yes.

You need to use SetItems.
This means you need to memorize the list, modify it and and reset it with SetItems.
