Question

I want to expand UITableView section where I have to show UITableViewCells. What should I do to achieve this?

Answer 1

• A simple implementation would be keep your cell height as zero for
  sections.
• Make the viewForSectionHeader touchable
• When you touch it, set proper height for cells under the section
• Write a logic for switching between sections

OR,

• On touching the section header reload the table with updated rows count for section touched.

Many other ways to do it. Apple example.
