Question

在我的tableview中，我在自定义单元格中有一个按钮

我使用代表对按钮进行操作

按钮图像仅在所选单元格上更改

我的问题是：

当我按下按钮时：

所选单元格正常工作且按钮更改正确（正确）
在所选单元格未更改按钮（已更正）之后的第二个
第三个单元格重复所选单元格的操作（错误）

这是无休止地重复不明白为什么该按钮应仅更改选定的单元格而不更改其他未选择的单元格

你能帮帮我吗？

-(void)ButtonPressedGoPoint:(FFCustomCellWithImage *)custom button:(UIButton *)gopointpressed {


    NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
    [numberFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"it_IT"]];
    NSNumber *likeCount = [numberFormatter numberFromString:custom.CountGoPoint.text];

    if (!custom.AddGoPoint.selected) {
        NSLog(@"TastoSelezionato");
        likeCount = [NSNumber numberWithInt:[likeCount intValue] + 1];
        custom.CountGoPoint.text = [NSString stringWithFormat:@"%@", likeCount];

       [custom.AddGoPoint setBackgroundImage:[UIImage imageNamed:@"FFIMG_Medal_Blu"] forState:UIControlStateNormal];
    }

    else  {
        if ([likeCount intValue] > 0) {
            likeCount = [NSNumber numberWithInt:[likeCount intValue] - 1];
            custom.CountGoPoint.text = [NSString stringWithFormat:@"%@", likeCount];
        }

        NSLog(@"TastoDeselezionato");
       [custom.AddGoPoint setBackgroundImage:[UIImage imageNamed:@"FFIMG_MedalADD"] forState:UIControlStateNormal];

    }

    custom.AddGoPoint.selected = !custom.AddGoPoint.selected;


}

这是我对tableview的实现

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    self.PostDetails = [ArrayforPost objectAtIndex:indexPath.row];
    static NSString *IdentificazioneCellaIMG = @"CellaIMG";
        FFCustomCellWithImage * CellaIMG = (FFCustomCellWithImage * )[self.FFTableView dequeueReusableCellWithIdentifier:IdentificazioneCellaIMG];
        if (CellaIMG == nil) {
            CellaIMG = [[FFCustomCellWithImage alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:IdentificazioneCellaIMG ];
        }

        CellaIMG.delegate = self;

     CellaIMG.tag = indexPath.row;
       [CellaIMG.AddGoPoint setTag:indexPath.row];

        if ([self AssignedGoPointToPost:self.PostDetails]) {
            CellaIMG.AddGoPoint.selected =YES;
             [CellaIMG.AddGoPoint setImage:[UIImage imageNamed:@"FFIMG_Medal_Blu"] forState:UIControlStateNormal];
        } else {
            CellaIMG.AddGoPoint.selected =NO;
             [CellaIMG.AddGoPoint setImage:[UIImage imageNamed:@"FFIMG_MedalADD"] forState:UIControlStateNormal];
        }

        NSString *FotoPostSocial = [self.PostDetails objectForKey:FF_POST_IMMAGINE];
        CellaIMG.FotoPost.file = (PFFile *)FotoPostSocial;
        [CellaIMG.FotoPost loadInBackground];
        CellaIMG.FotoPost.layer.masksToBounds = YES;
        CellaIMG.FotoPost.layer.cornerRadius = 2.0f;
        CellaIMG.FotoPost.contentMode = UIViewContentModeScaleAspectFill;

        CellaIMG.backgroundCell.layer.masksToBounds = YES;
        CellaIMG.backgroundCell.layer.cornerRadius = 2.0f;
        CellaIMG.backgroundCell.layer.borderColor = [UIColor colorWithRed:(219/255.0) green:(219/255.0) blue:(219/255.0) alpha:(1)].CGColor;
        CellaIMG.backgroundCell.layer.borderWidth = 1.0f;
        CellaIMG.backgroundCell.autoresizingMask = UIViewAutoresizingFlexibleHeight;
        CellaIMG.LeggiCommentoButton.layer.cornerRadius = 2.0f;
        CellaIMG.FotoProfilo.layer.masksToBounds = YES;
        CellaIMG.FotoProfilo.layer.cornerRadius = 25.0f;
        CellaIMG.FotoProfilo.contentMode = UIViewContentModeScaleAspectFill;

        CellaIMG.TestoPost.font = [UIFont fontWithName:@"Helvetica" size:14.0f];
        NSString *text = [self.PostDetails objectForKey:FF_POST_TEXT];
        CellaIMG.TestoPost.text = text;
        [CellaIMG.TestoPost setLineBreakMode:NSLineBreakByTruncatingTail];
        NSString *NomeUser = [[self.PostDetails objectForKey:FF_POST_UTENTE] objectForKey:FF_USER_NOMECOGNOME];
        CellaIMG.NomeUtente.text = NomeUser;
        NSString *ImmagineUtente = [[self.PostDetails objectForKey:FF_POST_UTENTE] objectForKey:FF_USER_FOTOPROFILO];
        CellaIMG.FotoProfilo.file = (PFFile *)ImmagineUtente;
        [CellaIMG.FotoProfilo loadInBackground];

        if (CellaSelezionata == indexPath.row) {
            CGFloat AltezzaLabel = [self valoreAltezzaCella: indexPath.row];
            CellaIMG.TestoPost.frame = CGRectMake(CellaIMG.TestoPost.frame.origin.x, CellaIMG.TestoPost.frame.origin.y, CellaIMG.TestoPost.frame.size.width, AltezzaLabel);  }

        else {
            CellaIMG.TestoPost.frame = CGRectMake(CellaIMG.TestoPost.frame.origin.x, CellaIMG.TestoPost.frame.origin.y, CellaIMG.TestoPost.frame.size.width, 65);
        }

        return CellaIMG;

        }
    }

UIButton没有选择正确的单元格
