iPhone - UITableViewController - 设置纵向和横向的节标题

Question

我有 UITableView 控制器，它使用自定义节标题视图。当我的设备是纵向时，它显示完美。当我的设备横向显示时，它又变得完美了。但是，当应用程序运行时方向发生变化时，它不会更新我的剖面视图。有什么问题吗？

使用以下代码，我向视图添加一个标签和两个按钮，并在“viewForHeaderInSection”中返回该视图。在调试过程中，我发现该方法被调用，但节标题视图没有更新。

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 80;
}

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    NSDictionary* dict = [threadsArray objectAtIndex:section];

    UIView* headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 80)];
    headerView.backgroundColor = [UIColor colorWithRed:0.0 green:0.0 blue:1.0 alpha:0.2];

    UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 15, self.view.frame.size.width - 98, 21)];
    newLabel.textColor = [UIColor blackColor];
    newLabel.font = [UIFont boldSystemFontOfSize:17];
    newLabel.text = [dict objectForKey:@"Name"];
    newLabel.backgroundColor = [UIColor clearColor];
    [headerView addSubview:newLabel];

    UIButton* addButton = [UIButton buttonWithType:UIButtonTypeContactAdd];
    addButton.frame = CGRectMake(self.view.frame.size.width - 88, 11, 29, 29);
    NSLog(@"%f %f %f %f",addButton.frame.origin.x,addButton.frame.origin.y, addButton.frame.size.width,addButton.frame.size.height);
    [addButton addTarget:self action:@selector(addThreadResponseClicked:) forControlEvents:UIControlEventTouchDown];
    [headerView addSubview:addButton];

    UIButton* expandCollapseButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [expandCollapseButton setImage:[UIImage imageNamed:@"Expand.png"] forState:UIControlStateNormal];
    expandCollapseButton.frame = CGRectMake(self.view.frame.size.width - 48, 11, 29, 29);
    NSLog(@"%f %f %f %f",expandCollapseButton.frame.origin.x,expandCollapseButton.frame.origin.y, expandCollapseButton.frame.size.width,expandCollapseButton.frame.size.height);
    [expandCollapseButton addTarget:self action:@selector(expandCollapseHeader:) forControlEvents:UIControlEventTouchDown];
    [headerView addSubview:expandCollapseButton];

    addButton.tag = expandCollapseButton.tag = section;
    return [headerView autorelease];
}

尝试设置视图 适当地自动调整遮罩大小：例如对于 headerView；

[headerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];

对于 addButton 和 ExpandCollapseButton 将 AutoresizingMask 设置为：

UIViewAutoresizingMaskFlexibleLeftMargin
