iOS UITable Row Deletion Woes...

[stephanos180]

Hi, everyone. I'm new to developing and am just trying to figure out how to delete rows. Can someone please help me figure out what's going on? The last line is causing the error... Thanks.

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

    if (editingStyle == UITableViewCellEditingStyleDelete) {
		Timer_ProAppDelegate *appDelegate = (Timer_ProAppDelegate*)[[UIApplication sharedApplication] delegate];
		[appDelegate.playlists removeObjectAtIndex:indexPath.row];
		[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
	}
	
}

Here's the console output.

2010-12-16 16:50:13.596 Timer Pro[44881:207] *** -[NSIndexPath count]: unrecognized selector sent to instance 0x39268c0

What is self.tableView when the error occurs? Often, "unrecognized selector" indicates an over-released object.
