objective-c tableview - 3 (swipe to delete)

You have to implement the necessary UITableViewDelegate and UITableViewDataSourcemethods.
First, add this:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        //remove the deleted object from your data source.
        //If your data source is an NSMutableArray, do this
        [self.dataArray removeObjectAtIndex:indexPath.row];
        [tableView reloadData]; // tell table to refresh now
