I am using Storyboard and UITableView without UINavigationController.
When tapping on any cell, it should bring user to a detail page. I can of course implement didSelectRowAtIndexPath:
But I wished to try something fairly different. I want to do it with a storyboard segue. I use prototype cell, and I can simply config a triggered segue on the cell. I can implement prepareForSegue:, but here's the problem, how can I know what cell has been selected?
The prepareForSegue:sender: method's sender parameter is the cell you are looking for. You can get it's index path by [self.tableView indexPathForCell:sender] (you may need a cast).
to get a clear view about how to use storyboard please check the following tutorial, how to use Storyboard
make sure that you read the second part too....this will give you a clear idea how to use, and the solution for your question also is there.
