Best Way To Implement Accordian in UITableView

Question

I want to implement accordian in only one of my UITableView rows (second row maybe) and I want to implement this without using any custom class or custom cell class. Clicking on the accordian row 'n' rows should be added under that row and I also want to track that rows didSelectRow() delegate method for that row and also for other rows independently. What is the best way to do it any help is appreciated.

I did this once with a Plain UITableView, without any custom cells, with the help of the method tableView:viewForHeaderInSection:. I used this method to design the headers of each section as a button to collapse/expand its rows.

You should maintain an array of booleans that indicates whether a specific section is expanded, i.e. its rows are visible. This array should start with all values false. Then when a section header is clicked, you should change its value in the array to true.

The method tableView:numberOfRowsInSection will return 0 if that section is collapsed or the number of rows in that section if it's expanded.

Finally you should use the reloadSections:withRowAnimation: method to animate the expanding/collapsing.
