Getting the exact location of a UITableViewCell

Question

Given a UITableView, how can I find the location of a specific UITableViewCell? In other words, I want to get its frame relative to my iPhone screen, n

Answer 1

For future viewers, I was having trouble getting a reliable frame for cells in a UITableView. I was trying to display a UIAlertController in ActionSheet style on an iPad which needs a popover presentation. In the end this approach yielded the best results:

// 44 is the standard height for a cell in a UITableView
// path is the index path of the relevant row
// controller is the UIAlertController
CGRect frame = CGRectZero;
frame.origin.y = 44 * path.row;
frame.origin.x = table.frame.origin.x;
frame.size = CGSizeMake(table.frame.size.width, 44);
controller.popoverPresentationController.sourceRect = [tableView convertRect:frame toView:self.view];
controller.popoverPresentationController.sourceView = self.view;
