表格视图中的重复单元格 [英] Repeated cells in table view

问题描述

这是我的cellForRowAtIndexPath.

this is my cellForRowAtIndexPath.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Maledetta"];
if (cell == nil) {
    UIViewController *c;
    if (!IS_IPAD) c = [[UIViewController alloc] initWithNibName:@"NewsRow" bundle:nil];
    else c = [[UIViewController alloc] initWithNibName:@"NewsRow_ipad" bundle:nil];
    cell = (NewsRowController*)c.view;

    if ([titleArray count] > 0) {
        [(NewsRowController*)cell setCellDataWithName:[titleArray objectAtIndex:indexPath.row]  
                                              andDate:[descArray objectAtIndex:indexPath.row] 
                                                  day:[dayArray objectAtIndex:indexPath.row]
                                                month:[monthArray objectAtIndex:indexPath.row]];
    }
    [c release];
}
return cell;
}

为什么只显示4行，之后又重复第4行直到第10行?

Why it show me only 4 row and after that repeat the first for fourth other time until ten???

Ah，[titleArray count]等于10. kCustomCellID是正确的.

Ah, [titleArray count] is equal to 10. kCustomCellID is correct.

谢谢.

推荐答案

如果在表的单元格队列中找不到该单元格，则只会填充该单元格.如果找到它，则不会用该indexPath.row值的内容覆盖它.

You're only populating the cell if it's not found in the table's cell queue. If it IS found, you're not overwriting it with the contents for that value of indexPath.row.

尝试以下方法:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Maledetta"];
if (cell == nil) {
    UIViewController *c;
    if (!IS_IPAD) c = [[UIViewController alloc] initWithNibName:@"NewsRow" bundle:nil];
    else c = [[UIViewController alloc] initWithNibName:@"NewsRow_ipad" bundle:nil];
    cell = (NewsRowController*)c.view;
    [c release];

 }

 if ([titleArray count] > 0) {
        [(NewsRowController*)cell setCellDataWithName:[titleArray objectAtIndex:indexPath.row]  
                                              andDate:[descArray objectAtIndex:indexPath.row] 
                                                  day:[dayArray objectAtIndex:indexPath.row]
                                                month:[monthArray objectAtIndex:indexPath.row]];
  }
  return cell;
}

此外，[titleArray count]的检查可能是多余的.您正在使用它来给出此表的部分中的单元格数量，对吗?如果那是零，它甚至都不会到达这里.

Also, the check of [titleArray count] is probably redundant. You're using that to give the number of cells in section for this table, right? If that's zero, it won't even get here.
