     NSString *identifier = @"reuseIdentifier"; 
     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; 

if (cell == nil) 
{ 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease]; 
    cell.selectionStyle = UITableViewCellSelectionStyleGray; 

    NSLog(@" row and section ===== %d,%d",indexPath.row,indexPath.section); 
    if(indexPath.section != 3) 
    { 
     UILabel *lbl_title = [[UILabel alloc] initWithFrame:(isiPad?CGRectMake(7,10,250,50):CGRectMake(70,40,340, 35))]; 
     [lbl_title setFont:[UIFont fontWithName:@"Verdana-Bold" size:(isiPad?20:13)]]; 
     lbl_title.backgroundColor = [UIColor clearColor]; 
     [lbl_title setTextColor:[UIColor blackColor]]; 

     lbl_title.tag = ((indexPath.section+1)*10)+indexPath.row;

     lbl_title.textAlignment = UITextAlignmentLeft; 
     [cell.contentView addSubview:lbl_title];

它重复因为您将它添加到单元格的contentview，然后您重新使用该单元格。而不是将其添加到单元格的contentView中，将该按钮添加为单元格附件。

cell.accessoryView = btn_register;

而在所有其他单元格中，将accessoryView设置为nil。

cell.accessoryView = nil;

你为什么不尝试电池的每个部分设置不同的标识符。您也可以使用使用[tableView dequeueReusableCellWithIdentifier:forIndexPath:

对“注册”单元使用不同的单元标识符应该工作。如果您使用容器来保存数据，您的代码将非常清晰，如NSDictionary。例如：

NSArray *account = @[@"Email", @"Password", @"Confirm password"]; 
NSArray *userInfo = @[@"First name", @"Last name", @"Gender", @"Nickname"]; 
// ... 
NSDictionary *data = @{@"Account": account, @"User Information": userInfo /* ... */};
