How to deal with dynamic Sections and Rows in iOS UITableView

Question

My issue

When I deal with UITableView, I basically have an Array table_data with my sections and rows.

Answer 1

It is a bad practice to use NSDictionary for storing data. Create new class for section (i.e. SectionData) and row (i.e. RowData). Your ViewController (or some other data provider) will keep array of SectionData, where SectionData keeps array of RowData. RowData may contain func for handling row selection, so in didSelectRowAtindexPath you just do something like this:

let rowData = rowDataAtIndexPath(indexPath)
rowData.tapHandler()

where rowDataAtIndexPath is your defined function that gives you data for indexPath.

When you need to remove some section, just remove it from array of sections and reload tableView.
