Question

旋转具有两个视图的视图控制器时，我有一个调整大小的问题，我使用翻转动画切换。如果我执行以下步骤，则会出现此问题：

查看桌面视图时旋转设备。
点击信息按钮。
旋转设备（infoView显示为拉伸）。
点击信息按钮（桌面视图显示为拉伸）

看起来未添加到superview的视图没有正确调整大小，因为它在旋转设备时不是复合视图的一部分。有没有办法让这个视图自动调整大小正确？

以下是代码示例

- (void)viewDidLoad {
    [super viewDidLoad];

    //background image
    backgroundImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bg-app.png"]];
    backgroundImageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
    [self.view addSubview: backgroundImageView];
    [backgroundImageView release];


    //infoView
    aboutImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"About.png"]];
    aboutImageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);

    //tableView
    self.tableView = [[[UITableView alloc ] initWithFrame:[[UIScreen mainScreen] bounds] style:UITableViewStylePlain] autorelease ];
    //set the rowHeight once for performance reasons.
    self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
    self.tableView.rowHeight = 75;
    self.tableView.backgroundColor = [UIColor clearColor];
    self.tableView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);                    

    self.tableView.delegate = self;
    self.tableView.dataSource = self;
    self.tableView.autoresizesSubviews = YES;

    //set the rowHeight once for performance reasons.
    [self.view addSubview: tableView];
    //[tableView release];

    [self.view setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];//for resizing on rotation

    //info button
    UIButton * infoDarkButtonType = [[UIButton buttonWithType:UIButtonTypeInfoLight] retain];
    infoDarkButtonType.frame = CGRectMake(0.0, 0.0, 25.0, 25.0);
    infoDarkButtonType.backgroundColor = [UIColor clearColor];
    [infoDarkButtonType addTarget:self action:@selector(infoAction:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *buttonInfo = [[UIBarButtonItem alloc] initWithCustomView:infoDarkButtonType];
    self.navigationItem.rightBarButtonItem = buttonInfo;
    [infoDarkButtonType release];   
    self.navigationItem.rightBarButtonItem = buttonInfo;
    [buttonInfo release];   

}

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return YES;

}


- (void)infoAction:(id)sender{ 
    NSLog(@"Clicked on the info button");


    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.75];     /* Sub. duration here */

    UIView *superview;
    if ((superview = [tableView superview])) {
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:superview cache:YES];
        [tableView removeFromSuperview];
        [superview addSubview:aboutImageView];
    } else if ((superview = [aboutImageView superview])) {
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:superview cache:YES];
        [aboutImageView removeFromSuperview];
        [superview addSubview:tableView];
    }

    [UIView commitAnimations];
}

尝试将代码放在viewWillAppear：animated中。每当您的视图出现时都会调用它。视图确实加载被调用一次。
