直接上代码了
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifiy = @"CELL";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifiy];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifiy];
}
cell.textLabel.text = _items[indexPath.row];
[_set addObject:indexPath];
NSLog(@"%@在唱歌", _items[indexPath.row]);
return cell;
}

for (NSIndexPath *anIndexPath in _set) {

}
