UITableView无法正确重新加载

如何解决UITableView无法正确重新加载

| 解决了 我的表格视图无法正确刷新数据。问题是我将文本标签内容编辑部分放在“ if（cell == nil）”条件内。 之前

{
    static Nsstring *CellIdentifier = @\"Cell\";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
        cell.textLabel.font = [UIFont boldSystemFontOfSize:16];
        cell.detailTextLabel.font = [UIFont systemFontOfSize:12];

        //This is where the mistake was
        cell.textLabel.text = [[array objectAtIndex:indexPath.row] valueForKey:@\"Key1\"];

    if ([[[array objectAtIndex:indexPath.row] valueForKey:@\"Key2\"] intValue] == 1)
    { cell.detailTextLabel.text =
        [Nsstring stringWithFormat:@\"%d sometext (%d sometext),%d sometext\",[[[array objectAtIndex:indexPath.row] valueForKey:@\"Key2\"] intValue],[[[array objectAtIndex:indexPath.row] valueForKey:@\"Key3\"] intValue],[[[array objectAtIndex:indexPath.row] valueForKey:@\"Key4\"] intValue]]; }
    else { cell.detailTextLabel.text =
        [Nsstring stringWithFormat:@\"%d sometext (%d sometext),[[[array objectAtIndex:indexPath.row] valueForKey:@\"Key4\"] intValue]]; }
    }

    return cell;
}

后

{
    static Nsstring *CellIdentifier = @\"Cell\";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
        cell.textLabel.font = [UIFont boldSystemFontOfSize:16];
        cell.detailTextLabel.font = [UIFont systemFontOfSize:12];
    }

    //This is what it should have looked like in the first place
    cell.textLabel.text = [[array objectAtIndex:indexPath.row] valueForKey:@\"Key1\"];

    if ([[[array objectAtIndex:indexPath.row] valueForKey:@\"Key2\"] intValue] == 1)
    { cell.detailTextLabel.text =
        [Nsstring stringWithFormat:@\"%d sometext (%d sometext),[[[array objectAtIndex:indexPath.row] valueForKey:@\"Key4\"] intValue]]; }
    return cell;
}
