Question

我尝试构建一个始终处于landsscape模式的应用程序。我做了通常的事情： plist添加了UIInterfaceOrientation / UIInterfaceOrientationLandscapeRight 在界面构建器中旋转了XIB，并在视图顶部显示了小箭头。

my code for launching:
- (void)applicationDidFinishLaunching:(UIApplication *)application {    
        [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];
    FlipViewController *flip = [[FlipViewController alloc] initWithNibName:@"FlipViewController" bundle:nil];
    [window addSubview:flip.view];
    [window makeKeyAndVisible];
}

但是当我尝试做“UIViewAnimationTransitionFlipFromLeft”时，页面从上到下而不是从右到左翻转。： - /

这是我用来翻转视图的代码：

[UIView beginAnimations:@"View Flip" context:nil];
    [UIView setAnimationDuration:1.25];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

    UIViewController *coming = nil;
    UIViewController *going = nil;
    UIViewAnimationTransition transition;

    if (self.blueViewController.view.superview == nil) 
    {   
        coming = blueViewController;
        going = yellowViewController;
        transition = UIViewAnimationTransitionFlipFromLeft;
    }
    else
    {
        coming = yellowViewController;
        going = blueViewController;
        transition = UIViewAnimationTransitionFlipFromRight;
    }

    [UIView setAnimationTransition: transition forView:self.view cache:YES];
    [coming viewWillAppear:YES];
    [going viewWillDisappear:YES];
    [going.view removeFromSuperview];
    [self.view insertSubview: coming.view atIndex:0];
    [going viewDidDisappear:YES];
    [coming viewDidAppear:YES];

    [UIView commitAnimations];

“窗口”似乎错过了这个事实，它处于landsscape模式。嗯。谁能发现我的错误？

记录方法无法实现。

您需要use CATransition。（CAT转换本身已记录在案，但翻转过渡不是。）

要使用翻转过渡，请将过渡的type设置为“oglFlip”，并将subtype设置为fromLeft / Top / Right / Bottom。

iphone视图翻转：viewflips从上到下而不是从右到左
