[tableView scrollToRowAtIndexPath:index
atScrollPosition:UITableViewScrollPositionTop
animated:YES];
This always work for 1st item. I want to have selected index in indexPathForRow.
Please help. Thanks.
回答1:
NSIndexPath *selectedIndexPath = [tableView indexPathForSelectedRow];
回答2:
Get current selected row. May be helpful if you have only one section.
- (NSUInteger)currentSellectedRowIndex
{
NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow];
if (selectedIndexPath) {
return selectedIndexPath.row;
}
else {
return NSNotFound;
}
}

Use this code
CGPoint location =[sender locationInView:self.tableView];
NSIndexPath *swipedIndexPath = [self.tableView indexPathForRowAtPoint:location];
UITableViewCell *swipedCell = [self.tableView cellForRowAtIndexPath:swipedIndexPath];
NSIndexPath *indexPath = [self.tableView indexPathForCell:swipedCell];
回答4:
In didSelectRowAtIndexPath, set an interface declared NSIndexPath as the indexpath returned. Then you can scroll to that variable. If you need help, comment and I can give some sample code.
回答5:
Swift 4.2
let selectedIndexPath = tableView.indexPathForSelectedRow
which is an optional return value.
