This sample project shows how to implement Expandable/Collapsable TableView in iOS. This Project expands and collapses table view cells on selecting a cell or row of table or by tapping on a button on the cell in tableview
I have downloaded your project and run with the iPad simulator (iPad2, iPad Air, iPad Ratina) , it crashes. Here is the error description - Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "BYZ-38-t0r-view-8bC-Xf-vdC" nib but didn't get a UITableView.'
After debugging found error that the UITableView is missing inside iPad storyboard, so added it and connected it solved the issue. Kindly fix it and update new demo.
