iOS--當cell上顯示不同數量圖片的時候重用

標籤：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    //標識符    static NSString *iden = @"cardsCell";    CardsCell *cell = [tableView dequeueReusableCellWithIdentifier:iden];    Cards *cards = [self.cardsArr objectAtIndex:indexPath.row];   //cell為空白就建立    if (cell == nil) {        cell = [[CardsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:iden];    }else {   //如果存在cell需要把之前添加的會變化的控制項刪除        //刪除cell上添加的圖片        [cell.photoGroup removeFromSuperview];    }    cell.cards = cards;;        return cell;}

在自訂cell裡

- (void)setCards:(Cards *)cards {    if (_cards != cards) {        _cards = cards;    }    //給cell控制項賦值    [self.avaImageView sd_setImageWithURL:[NSURL URLWithString:_cards.avaImageUrl] placeholderImage:[UIImage imageNamed:@"72tx.png"]];    self.usernameLabel.text = _cards.username;    self.commentLabel.text = [NSString stringWithFormat:@"%ld",_cards.replyArr.count];    self.titleLabel.text = _cards.title;    self.timeLabel.text = _cards.time;    self.contextLabel.text = _cards.context;    //判斷圖片數組數量，大於0就根據數量建立，否則不建立    if (_cards.imageArr.count > 0) {        //圖片瀏覽，用了一個圖片瀏覽器SDPhotoGroup，繼承UIView        self.photoGroup = [[SDPhotoGroup alloc] initWithFrame:CGRectMake1(0, 100, 105*_cards.imageArr.count, 60)];        NSMutableArray *temp = [NSMutableArray array];        [_cards.imageArr enumerateObjectsUsingBlock:^(NSString *src, NSUInteger idx, BOOL *stop) {            SDPhotoItem *item = [[SDPhotoItem alloc] init];            item.thumbnail_pic = src;            [temp addObject:item];        }];        self.photoGroup.photoItemArray = [temp copy];        [self.contentView addSubview:self.photoGroup];    }}
