Releasing unused UITableViewCells

gistfile1.m

-(void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    
    NSMutableDictionary* cells = [self.tableView valueForKey:@"_reusableTableCells"];
    for (UITableViewCell* cell in self.tableView.visibleCells) {
        if ([cell.reuseIdentifier isEqualToString:@"Text"]) {
            return;
        }
    }
    [cells removeObjectForKey:@"Text"];
    [self.tableView setValue:cells forKey:@"_reusableTableCells"];
}

When your UITableView displays different kind of UITableViewCells it's likely that there are cells that aren't displayed often. However, the TableView doesn't release them. With this little hack you can release the currently unused cells.
