Iphone应用程序在iOS 4.3中因EXC_BAD_ACCESS错误而崩溃,但在以前的版本中运行正常

Question

我创建了一个苹果批准的应用程序,目前可以在appstore中购买.但是在4.3更新之后,当使用EXC_BAD_ACCESS错误滚动UITableView时它会崩溃.NSZombieEnabled = YES,将使应用程序再次运行,但这当然不是解决方案;)在以下行的Main类中报告错误:

int retVal = UIApplicationMain(argc, argv, nil, nil);

堆栈跟踪也无法帮助我:

有人可以帮我解决这个问题吗？我正试图让这个工作2天了:(

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";

    CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
        cell = customCell;
        self.customCell = nil;
    }
    int num = indexPath.row;

    if (indexPath.section != 0) {
        for (int i=1; i <= indexPath.section; i++) {
            num = (num + [[sectorSize objectAtIndex:(i-1)] intValue]);
        }
    }
    // Configure the cell...
        cell.tijdLabel.text = [NSString stringWithFormat:@"%@ - %@", [tijdBeginList objectAtIndex:num], [tijdEindList objectAtIndex:num]];
        cell.lesVormLabel.text = [lesVormList objectAtIndex:num];
        cell.docentLabel.text = [docentList objectAtIndex:num];
        cell.lokaalLabel.text = [lokaalList objectAtIndex:num];
        cell.opmerkingLabel.text = [opmerkingList objectAtIndex:num];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
    return cell;
}

检查Custom Cell实现的dealloc方法,确保[super dealloc]是最后一条指令.我有一个类似的问题,结果发现我在发布一些视图标签和其他项目之前调用了[super dealloc].
