Iphone 如何同时翻转两个视图？

我尝试在一个屏幕上点击一个按钮来翻转两个视图，也就是说，我希望同时拥有多个动画（例如：iPhone音乐播放器，其中按钮和视图同时翻转）

p、 我不想一个接一个地设置视图的动画，它应该一起完成

这是我使用的代码，请帮我解决

[UIView beginAnimations:nil context:nil];
[UIView animateWithDuration:0.8 animations:^{

    if (viewDisplay) 

    {

        [fareView removeFromSuperview];

        [containerView addSubview:mapView];

        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:containerView cache:YES];

        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:buttonView cache:YES];

        viewDisplay = FALSE;

        swapLabel.text = @"Fare View";

        [mapOrFare setImage:[UIImage imageNamed:@"original_icon.png"] forState:UIControlStateNormal];

    }

    else

    {

        [mapView removeFromSuperview];

        [containerView addSubview:fareView];

        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:containerView cache:YES];

        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:buttonView cache:YES];

        viewDisplay = TRUE;

        swapLabel.text = @"Map View";

        [mapOrFare setImage:[UIImage imageNamed:@"Map.png"] forState:UIControlStateNormal];

    }

}];

[UIView commitAnimations];

只需使用块动画，它应该没有问题的工作

[UIView animateWithDuration:myDuration
    animations:^{
        <animation 1 code>;
        <animation 2 code>;
}];

[UIView animateWithDuration:myDuration
动画：^{
;
;
}];

只需使用块动画，就可以正常工作

[UIView animateWithDuration:myDuration
    animations:^{
        <animation 1 code>;
        <animation 2 code>;
}];

[UIView animateWithDuration:myDuration
动画：^{
;
;
}];

假设

bgView1

和

bgView2

是要翻转的视图，如下所示；你应该能够把动画师的代码一个接一个地放进去，一切都会好的。请参见下面的示例

-(void)flipViews {

    CGContextRef context = UIGraphicsGetCurrentContext();
    [UIView beginAnimations:nil context:context];
    [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:bgView1 cache:YES];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationDelegate:self];

    [bgView1 exchangeSubviewAtIndex:0 withSubviewAtIndex:1];

    [UIView commitAnimations];


    context = UIGraphicsGetCurrentContext();
    [UIView beginAnimations:nil context:context];
    [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:bgView2 cache:YES];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationDelegate:self];

    [bgView2 exchangeSubviewAtIndex:0 withSubviewAtIndex:1];

    [UIView commitAnimations];

}

我尝试使用[UIView beginAnimation….]设置两个子视图的动画。[UIView commitAnimation]块，但只有一个视图设置了动画。另一个只是出现了。我尝试使用[UIView beginAnimation….]设置两个子视图的动画。[UIView commitAnimation]块，但只有一个视图设置了动画。另一个简单地出现了。没有用，因为动画代码是关键。动画代码对于这个代码示例是什么样子的？没有用，因为动画代码是关键。动画代码对于这个代码示例是什么样子的？？
