I want to make picker with 2 lines, I tried it like <a href="https://stackoverflow.com/questions/15395813/uipickerview-using-custom-views-for-multi-line-rows-need-layout-advice">a link</a> , but I can not understand what I need to do: create a view and 2 label on it, when I add labels coordinates to code, but selection field still like it as default. How can I change selection field size? And text in selection field have bigger size when other lines.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
