tableviewcell的详解

[待解决问题]
今天在做项目时，遇到个问题。希望大神来说说原因。我在进行tableview的刷新时，刷新后没进入cell==nil这个判断，而是进入了cell != nil,求解释！如果是在缓存池中找到的话，那么理由呢？reloaddata之后不是应该进入cell == nil这个判断吗？求大神解释！！
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *identifier = @"cell"; if (indexPath.section == 0) { FirstPersonalInformationTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; if (cell == nil) { cell = [[FirstPersonalInformationTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier]; cell.firstLabel.text = self.firstNameArr[indexPath.row]; if (indexPath.row == 0) { cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.iconImage.image = [UIImage imageNamed:@"userImage.png"]; }else if (indexPath.row == 1){ cell.secondLabel.text = [[[PreferenceData GetToPreferencePathDic:DIC WithGetKey:@"loginDic"] objectForKey:@"username"] stringByAppendingString:@".hart"]; }else if (indexPath.row == 2){ cell.fifthLabel.text = @"第二行"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; }else if (indexPath.row == 3){ NSLog(@"%@", self.initialNationalityName); cell.fifthLabel.text = self.initialNationalityName; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; }else if (indexPath.row == 4){ cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.QrCodeImage.image = [UIImage imageNamed:@"twoCode.png"]; } } return cell;
以上就是我写的cellforrow代码。
