目标 C：如何解决代码中的泄漏（来自仪器的结果）

我为我的应用程序运行了仪器（其中包含 UITableView）并得到了以下结果

每次单元格变得可见时，单元格将调用方法 [UICustomButton SetButtonWithAnswer....]

编辑：添加了更多屏幕截图

问题是我不确定到底是什么导致了泄漏。我已经在代码中释放了所有的分配初始化。为什么还是漏水？

对此的任何建议将不胜感激！

EDIT:

我添加了 UICustom 按钮，如下所示

if (cell == nil)
{
    cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:PlaceholderCellIdentifier] autorelease];
    //Add like button
    UICustomButton *likeButton = [[UICustomButton alloc]init];
    likeButton.tag = 7;

    //Add comment button
    UICustomButton *commentButton = [[UICustomButton alloc]init];
    commentButton.tag = 8;

    //Add answer too button
    UICustomButton *answerButton = [[UICustomButton alloc]init];
    answerButton.tag = 9;

    [self.contentView addSubview:likeButton];
    [self.contentView addSubview:commentButton];
    [self.contentView addSubview:answerButton];

    [likeButton release];
    [commentButton release];
    [answerButton release];
}


//Set like button
UICustomButton *thisLikeButton = (UICustomButton *)[self.contentView viewWithTag:7];
[thisLikeButton setButtonWithAnswer:self.answerForCell buttonType:@"like" navcon:self.navcon andFrame:CGRectMake(CELL_TEXT_LEFT_MARGIN, totalCommentLabelHeight + CELL_SPACING*4, 45, CELL_BUTTON_HEIGHT)];
thisLikeButton.imageView.image = [UIImage imageNamed:@"heart.png"];


//Set comment button
UICustomButton *thisCommentButton = (UICustomButton *)[self.contentView viewWithTag:8];
 [thisCommentButton setButtonWithAnswer:self.answerForCell buttonType:@"comment" navcon:self.navcon andFrame:CGRectMake(CELL_TEXT_LEFT_MARGIN + 45 + 5, totalCommentLabelHeight + CELL_SPACING*4, 80, CELL_BUTTON_HEIGHT)];
thisCommentButton.imageView.image = [UIImage imageNamed:@"chat.png"];

//Set answer button
UICustomButton *thisAnswerButton = (UICustomButton *)[self.contentView viewWithTag:9];    
[thisAnswerButton setButtonWithAnswer:self.answerForCell buttonType:@"join in" navcon:self.navcon andFrame:CGRectMake(1.5*CELL_TEXT_LEFT_MARGIN + 45 + 5 + 80 + 5, totalCommentLabelHeight + CELL_SPACING*4, 60, CELL_BUTTON_HEIGHT)];
thisAnswerButton.imageView.image = [UIImage imageNamed:@"beer-mug_white.png"];

里面的每个分配/初始化setButton:…需要重新考虑。你做not想要重新创建这些视图只是为了设置值。

if (self.imageView == nil) {
  UIImageView tempImageView = alloc/init …
  self.imageView = tempImageView;
  [tempImageView release];
}

self.imageView.image = self.image;
