在cell里面

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
     
     MoneyListCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellID"forIndexPath:indexPath];
     MoneyListModel *MoneyList = arrModel[indexPath.row];
     cell.title.text = MoneyList.goods_name;
     cell.money.text = MoneyList.money;
     NSDate *date = [NSDate dateWithTimeIntervalSince1970:[MoneyList.addtime doubleValue]];
     NSDateFormatter *forMatter = [[NSDateFormatter alloc] init];
     [forMatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
     cell.time.text = [forMatter stringFromDate:date];
     cell.selectionStyle = UITableViewCellSelectionStyleNone;
     
     return cell;
}

单独拿出来

NSDate *date = [NSDate dateWithTimeIntervalSince1970:[MoneyList.addtime doubleValue]];
     NSDateFormatter *forMatter = [[NSDateFormatter alloc] init];
     [forMatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
     cell.time.text = [forMatter stringFromDate:date];
