Question

我试图通过单击按钮在一个屏幕上翻转两个视图，即我想同时拥有多个动画（例如：iPhone音乐播放器，其中按钮和视图同时翻转）

p.s-i不想一个接一个地制作视图，它应该一起完成

修改

这是我使用的代码，请帮帮我

[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];

Answer 1

假设bgView1和bgView2是要翻转的视图，如下所示;你应该能够一个接一个地放置动画代码，它应该都可以正常工作。请参阅下面的示例

-(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];

}

Answer 2

只需使用块动画，它应该没有任何问题。

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

如何一次翻转两个视图？
