How can I tell if a UITableView contains a specific NSIndexPath?

Question

Here is the code I\'m using:

if (appDelegate.currentMainIndexPath != nil /* && doesPathExistInTableView */)
{
    [tblView scrollToRowAtIndexPath:appDele         


        

Answer 1

This is how you do it:

indexPath.row < [self.tableView numberOfRowsInSection:indexPath.section]

In context:

if (indexPath.row < [self.tableView numberOfRowsInSection:indexPath.section]) {
    [self.tableView scrollToRowAtIndexPath:indexPath
                          atScrollPosition:UITableViewScrollPositionTop
                                  animated:YES];
}

Inserted into your code:

if (appDelegate.currentMainIndexPath != nil &&
    indexPath.row < [tblView numberOfRowsInSection:indexPath.section]) {
    [tblView scrollToRowAtIndexPath:appDelegate.currentMainIndexPath
                   atScrollPosition:UITableViewScrollPositionTop
                           animated:NO];
    appDelegate.currentMainIndexPath = nil;
}

You can also use UITableView's numberOfRowsInSection method.
