Question

我已经设置了一个包含两个视图的多视图应用程序。可以使用每个视图中的按钮切换视图（有两个单独的操作）。我正在使用动画UIViewAnimationTransitionFlipFromRight，当我从第一个视图转到第二个视图时，我将出现在翻转动画后面的视图。我希望它只是白色的。任何帮助表示赞赏。

这是切换视图的操作：

    - (IBAction)switchViewsOne:(id)sender
{

if (self.uLViewController == nil)

{

ULViewController *uLController = 

[[ULViewController alloc]

 initWithNibName:@"ULView" 

bundle:nil];

self.uLViewController = uLController;

[uLController release];

}

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

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

    if (uLViewController.view.superview == nil)
    {
        comming = uLViewController;
        going = mainViewController;
        transition = UIViewAnimationTransitionFlipFromLeft;
    }

    [UIView setAnimationTransition: transition forView:self.view
                             cache:YES];
    [comming viewWillAppear:YES];
    [going viewWillDisappear:YES];
    [going.view removeFromSuperview];
    [self.view insertSubview: comming.view atIndex:10];
    [going viewDidDisappear:YES];
    [comming viewDidAppear:YES];


    [UIView commitAnimations];
}

Answer 1

你可以尝试使用addSubView，它只是将它添加到堆栈的顶部。

Answer 2

如果comming.view为nil

，则可能是这种错误

[self.view insertSubview: comming.view atIndex:10];

检查，可能你的笔尖没有正确加载

ULViewController *uLController = [[ULViewController alloc] initWithNibName:@"ULView" bundle:nil];
NSLog(@"Loaded controller %@:", uLController);

iPhone视图出现在动画背后
