1壤躲，NSString *CellIdentifier = [NSString stringWithFormat:@"Cell%d%d", [indexPath section], [indexPath row]];//以indexPath來唯一確定cell
UITableViewCell?*cell?=?[tableView?dequeueReusableCellWithIdentifier:CellIdentifier];?//出列可重用的cell
if?(cell?==?nil)?{
cell?=?[[UITableViewCell?alloc]?initWithStyle:UITableViewCellStyleDefault?reuseIdentifier:CellIdentifier];
}
2搅幅，NSString*cellID = [NSString stringWithFormat:@"%ld", (long)indexPath.row];
cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if(cell ==nil) {
cell= (YiWenTableViewCell *)[[[NSBundle? mainBundle]? loadNibNamed:@"YiWenTableViewCell" owner:self options:nil]? lastObject];
[cell setValue:cellID forKey:@"reuseIdentifier"];
}
