I have got the following code: – (void)tableView:(UITableView *)tableView commitEditingStyle: (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

  • 0

I have got the following code:

 - (void)tableView:(UITableView *)tableView commitEditingStyle:   (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

 if (editingStyle == UITableViewCellEditingStyleDelete) {
 [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone];
 [[delegate contentArray] removeObjectAtIndex:indexPath.row];
 [self.tableView reloadData];
}
if (editingStyle == UITableViewCellEditingStyleInsert) {
}
}

Now when I run it, the edit button works and the delete interface comes up, but I get a SIGABRT error when I press the delete button.

I am not sure how to read the log files yet, but if you need them, tell me how to get them to you:-)

EDIT:

I have posted the console log here:

    This is the key line from the log:

    Terminating app due to uncaught  exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of    rows in section 0.  The number of rows contained in an existing section after the update (4)  must be equal to the number of rows contained in that section before the update (4), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted).'

    mattjgalloway is 100% correct about the solution. I hope he posts that as an answer so that he can get credit for it.
