Question

我的tableview有问题。让我先描述一下情况。我有一个顶部2 buttons（日历和排名）的视图。在这两个按钮下面，我有一个tableview。当我按下按钮时，我设置tableview's tag ( 1 or 2 )，然后重新加载tableview的数据。

在我的排名中，我将一个特定单元格的文本颜色设为蓝色。但是当我刷新时，其他单元格的文本会变成蓝色。

现在我的cellForRowAtIndex我有很多代码。因为我不知道问题在哪里，我将在这里发布所有代码。我希望你不要打扰。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //standard cell
    static NSString *simpleTableIdentifier = @"KalenderCell";
    KalenderCell *cell = (KalenderCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if ((cell == nil) || (![cell isKindOfClass:KalenderCell.class]))
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"KalenderCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }

    //Cells for button 2
    if(self.tableView.tag == 2){
        static NSString *simpleTableIdentifier = @"KlassementCell";

        KlassementCell *cell = (KlassementCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
        if ((cell == nil) || (![cell isKindOfClass: KlassementCell.class]))
        {
            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"KlassementCell" owner:self options:nil];
            cell = [nib objectAtIndex:0];
        }

        Klassement *klassement = [self.fetchedResultsController objectAtIndexPath:indexPath];
        NSData *dataIcon = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:klassement.icon]];
        UIImage *imgIcon = [UIImage imageWithData:dataIcon];


        cell.lblPosition.text       = klassement.position;
        cell.lblName.text           = klassement.name;
        cell.lblgamesPlayed.text    = klassement.gamesPlayed;
        cell.lblGamesWon.text       = klassement.gamesWon;
        cell.lblGamesTied.text      = klassement.gamesTied;
        cell.lblGamesLost.text      = klassement.gamesLost;
        cell.lblGoalsPos.text       = klassement.goalsPos;
        cell.lblGoalsNeg.text       = klassement.goalsNeg;
        cell.lblGoalsDiff.text      = [NSString stringWithFormat:@"%@", klassement.goalsDiff];
        cell.lblPoints.text         = klassement.points;
        cell.imgClub.image          = imgIcon;

        if([klassement.name isEqualToString:@"KRC Genk"]){
            cell.lblPosition.textColor      = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblName.textColor          = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblgamesPlayed.textColor   = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblGamesTied.textColor     = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblGamesLost.textColor     = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblGoalsDiff.textColor     = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblGoalsNeg.textColor      = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblGoalsPos.textColor      = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblPoints.textColor        = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            cell.lblGamesWon.textColor      = [UIColor colorWithRed:(56/255.0) green:(119/255.0) blue:(189/255.0) alpha:100] ;
            return cell;
        }

        return cell;

        //Cells for button 1
    }else if(self.tableView.tag == 1){
        static NSString *simpleTableIdentifier = @"KalenderCell";

        KalenderCell *cell = (KalenderCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
        if ((cell == nil) || (![cell isKindOfClass:KalenderCell.class]))
        {
            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"KalenderCell" owner:self options:nil];
            cell = [nib objectAtIndex:0];
        }

        Kalender *kalender = [self.fetchedResultsController objectAtIndexPath:indexPath];

        NSData *imgDataHome = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:kalender.homeIcon]];
        NSData *imgDataAway = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:kalender.awayIcon]];

        UIImage *imgHome = [UIImage imageWithData:imgDataHome];
        UIImage *imgAway = [UIImage imageWithData:imgDataAway];

        // Then configure the cell using it ...
        if([kalender.type isEqualToString:@"JPL"]){
            _imgType = [UIImage imageNamed:@"jupiler.png"];
        }else if ([kalender.type isEqualToString:@"EU"]){
            _imgType = [UIImage imageNamed:@"europa.jpg"];
        }else {
            _imgType = nil;
        }

        cell.lblHome.text           = kalender.home;
        cell.lblHomeScore.text      = kalender.homeScore;
        cell.lblAwayScore.text      = kalender.awayScore;
        cell.lblAway.text           = kalender.away;
        cell.lblDate.text           = kalender.date_text;
        cell.lblHour.text           = kalender.hour;
        cell.img_Home.image         = imgHome;
        cell.img_Away.image         = imgAway;
        cell.img_type.image         = _imgType;


        return cell;
    }


    return cell;

}

另一个问题是，有时单元格会在tableview中复制2到3次，但是当我刷新时，tableview又回来了。

我知道这是很多代码。但我希望你能帮助我！

亲切的问候，并提前多多感谢！

Answer 1

在创建新单元格的else部分添加以下行：

[cell.contentView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];

您可以看到我的回答here

试试这个：

if ((cell == nil) || (![cell isKindOfClass:KalenderCell.class]))
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"KalenderCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];
}
else
{
   [cell.contentView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
}

Answer 2

在波纹管条件下设置蓝色

    if([klassement.name isEqualToString:@"KRC Genk"]){
      /// set blue color 
    }

因为它添加了黑色部分

像吼声一样......

         else{
            cell.lblPosition.textColor      = [UIColor blackColor] ;
            cell.lblName.textColor          = [UIColor blackColor] ;
            cell.lblgamesPlayed.textColor   = [UIColor blackColor] ;
            cell.lblGamesTied.textColor     = [UIColor blackColor] ;
            cell.lblGamesLost.textColor     = [UIColor blackColor] ;
            cell.lblGoalsDiff.textColor     = [UIColor blackColor] ;
            cell.lblGoalsNeg.textColor      = [UIColor blackColor] ;
            cell.lblGoalsPos.textColor      = [UIColor blackColor] ;
            cell.lblPoints.textColor        = [UIColor blackColor] ;   
            cell.lblGamesWon.textColor      = [UIColor blackColor] ;
            return cell;
         }

使用具有不同表视图标记的tableview的问题
