根据方向在 XIB 中切换视图

Question

对于每个方向，我的 XIB 中有两个视图。它们相似但不同，所以我不能依赖自动调整大小。我想根据方向切换这些视图。当我使用方法 didRotateFromInterfaceOrientation 时，当它从 Portrait 旋转时，它将显示横向视图，当它旋转到 PortraitUpsideDown 时，这是一个问题。
如果我修改 willRotateToInterfaceOrientation 的代码，那么在 LandscapeView 中，PortraitView 对用户隐藏，但是当用户单击按钮时，它们不会显示为灰色以显示它们已被单击，并且它的应用程序响应就像用户正在单击按钮一样在纵向视图中。

我是否以正确的方式解决这个问题？我需要做什么来修复这些错误。我更喜欢使用 willRotateToInterfaceOrientation 方法。

谢谢，

代码：

- (void)viewDidLoad {
... 
    for (UIView *v in self.view.subviews) {
        v.autoresizingMask = UIViewAutoresizingNone;
    }
...
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
        return YES;
    }

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {

    if(fromInterfaceOrientation == UIInterfaceOrientationPortrait 
       || fromInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
        //Add landscape view
        if(![landscapeView superview]){
            for (UIView *v in landscapeView.subviews) {
                v.autoresizingMask = UIViewAutoresizingNone;
            }
            //No effect after testing
            [UIView beginAnimations:nil context:nil];
            [UIView setAnimationDuration:0.33];
            [self.view addSubview:landscapeView];
            [UIView commitAnimations];
        }
    }else {
        if([landscapeView superview]){
            [landscapeView removeFromSuperview];
        }
    }
}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft 
       || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        //Add landscape view
        if(![landscapeView superview]){
            for (UIView *v in landscapeView.subviews) {
                v.autoresizingMask = UIViewAutoresizingNone;
            }
            //No effect after testing
            [UIView beginAnimations:nil context:nil];
            [UIView setAnimationDuration:0.33];
            [self.view addSubview:landscapeView];
            [UIView commitAnimations];
        }
    }else {
        if([landscapeView superview]){
            [landscapeView removeFromSuperview];
        }
}
}

在你看来确实加载了

[[NSNotificationCenter defaultCenter] addObserver:self
           selector:@selector(willRotateToInterfaceOrientation:)
           name:@"UIDeviceOrientationDidChangeNotification" object:nil];

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft) {
        viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
        newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
        [self presentModalViewController:newView animated:YES];
        [newView release];

    }

    if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) {
        viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
        newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
        [self presentModalViewController:newView animated:YES];
        [newView release];

    }

    if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) {
        viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
        newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
        [self presentModalViewController:newView animated:YES];
        [newView release];

    }

    if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown) {
        viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
        newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
        [self presentModalViewController:newView animated:YES];
        [newView release];

    }
}
