Iphone UIView翻转转换仅发生一次

我有一个包含两个其他UIView的UIView。我试着让它们在按下按钮时翻转。下面是我在按钮操作中翻转它们的代码：

- (IBAction)btMapView:(id)sender
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1];
    [UIView transitionFromView:mView1 toView:m_MapView duration:3 options:UIViewAnimationOptionTransitionFlipFromLeft completion:NULL];
    [UIView commitAnimations];
}

- (IBAction)btListView:(id)sender
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1];
    [UIView transitionFromView:m_MapView toView:mView1 duration:3 options:UIViewAnimationOptionTransitionFlipFromRight completion:NULL];
    [UIView commitAnimations];
}

我在viewDidLoad中初始化m_MapView，如下所示：

- (void)viewDidLoad
{
    [super viewDidLoad];

    [m_MapView setMapType:MKMapTypeHybrid];
    [m_MapView setZoomEnabled:YES];
    [m_MapView setScrollEnabled:YES];
    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
    region.center.latitude = 42.761738 ;
    region.center.longitude = -71.463180;
    region.span.longitudeDelta = 0.01f;
    region.span.latitudeDelta = 0.01f;
    [m_MapView setRegion:region animated:YES];
    m_MapView.showsUserLocation = YES;
    [m_MapView setDelegate:self];

    CLLocationCoordinate2D zoomLocation;
    zoomLocation.latitude = 42.761738;
    zoomLocation.longitude = -71.463180;

    MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(zoomLocation, .25*METERS_PER_MILE, .25*METERS_PER_MILE);
    MKCoordinateRegion adjustedRegion = [m_MapView regionThatFits:viewRegion];

    m_MapView.autoresizingMask =
    (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

    [m_MapView setRegion:adjustedRegion animated:YES];

    DisplayMap * myLoc = [[DisplayMap alloc] init];
    myLoc.title = @"myLoc";
    myLoc.subtitle = @"Main Office";
    myLoc.coordinate = region.center;
    [m_MapView addAnnotation:myLoc];
}

我的第二个视图上有一个标签

当我按下btMapView按钮时，另一个视图会发生翻转，但当我按下btListView按钮时，它不会向后翻转

谁能解释一下我会做错什么

谢谢你的帮助

编辑：

将我的代码从viewDidLoad移动到ViewWillDisplay，并将两个按钮方法更改为：

- (IBAction)btMapView:(id)sender
{
    [UIView transitionFromView:mView1
                        toView:m_MapView
                      duration:1
                       options:UIViewAnimationOptionTransitionFlipFromLeft | UIViewAnimationOptionShowHideTransitionViews 
                    completion:nil];
}

- (IBAction)btListView:(id)sender
{
    [UIView transitionFromView:m_MapView
                        toView:mView1
                      duration:1
                       options:UIViewAnimationOptionTransitionFlipFromRight | UIViewAnimationOptionShowHideTransitionViews 
                    completion:nil];
}

请尝试以下操作：

- (IBAction)btMapView:(id)sender
{
    [mView1.superview addSubview: m_MapView];
    [UIView transitionFromView:mView1 toView:m_MapView duration:3 options:UIViewAnimationOptionTransitionFlipFromLeft | UIViewAnimationOptionShowHideTransitionViews completion: ^(BOOL finished) { [mView1 removeFromSuperview]; }];
}

- (IBAction)btListView:(id)sender
{
    [m_MapView.superview addSubview: mView1];
    [UIView transitionFromView:m_MapView toView:mView1 duration:3 options:UIViewAnimationOptionTransitionFlipFromRight | UIViewAnimationOptionShowHideTransitionViews completion:^(BOOL finished) { [m_MapView removeFromSuperview]; }];
}

在UIButton操作时使用以下代码，它工作正常：

    SecondView *second=[[SecondView alloc] init];
    [UIView transitionFromView:self.view toView:second.view duration:2.0 options:UIViewAnimationOptionTransitionFlipFromRight completion:nil];

---

这里SecondView是SecondView的名称。

您不需要将transitionFromView放在begin/commitAnimations对中…因此，我确实删除了这些行，只留下transitionFromView，它会翻转一次，然后再翻转回来，但之后视图是空的。是的，我确实这样做了，但是视图转换了一次，然后视图变成了空白。@LilMoke:你真的试过我的代码吗？我添加了一个完成块。试试看。我添加了你发送的代码，但它做了同样的事情。。。第一次后视图为空。@LilMoke。。。编辑了我的代码。。试试看。如果那样不行，我就迷路了。。因为它在我的机器上工作DHmm我还注意到我在选项中使用了UIViewAnimationOptions ShowHideTransitionViews。。将编辑以上内容。
