How can I keep track of the index path of a button in a table view cell?

Question

I have a table view where each cell has a button accessory view. The table is managed by a fetched results controller and is frequently reordered. I want to be able to press

Answer 1

I don't know why I need to call the method superview twice to get the UITableViewCell.

Update:

Thank for Qiulang, now I got it.

"That's because SDK now has added a private class called UITableViewCellContentView for UITableViewCell, which is button's superview now." – Qiulang

UIButton *button = (UIButton *)sender;
UITableViewCell *cell = (UITableViewCell *)button.superview.superview;
UITableView *curTableView = (UITableView *)cell.superview;
NSIndexPath *indexPath = [curTableView indexPathForCell:cell];
