iOS - How can I get the IndexPath of the last item in a tableview?

Question

I would like to automatically scroll to the end of a table view.

[tableView scrollToRowAtIndexPath:lastIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES]; 

Given that I know how many item are in the tableview using:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 

How can I get the IndexPath * to the last item in this tableView? This is needed so that I can provide it as an argument to scrollToRowAtIndexPath:atScrollPosition:animated

Thanks!

To get a reference to the last row in the last section…

// First figure out how many sections there are NSInteger lastSectionIndex = [tableView numberOfSections] - 1;  // Then grab the number of rows in the last section NSInteger lastRowIndex = [tableView numberOfRowsInSection:lastSectionIndex] - 1;  // Now just construct the index path NSIndexPath *pathToLastRow = [NSIndexPath indexPathForRow:lastRowIndex inSection:lastSectionIndex];
