Ios 翻转和替换UIView

我在视图控制器中添加了一个

ui视图

，作为子视图，我试图将其翻转并替换为其他视图

[UIView transitionFromView:self.testBlueTicket toView:self.testOrangeTicket duration:2 options:UIViewAnimationOptionTransitionFlipFromRight completion:^(BOOL finished) {
        
}];

问题是整个viewcontroller正在翻转，而不仅仅是我想要翻转和替换的特定视图

---

我已经搜索了文档，没有找到任何特定的解决方案。如果您有任何建议，我们将不胜感激。

使用

[UIView transitionFromView…

为superview设置动画

因此，将您的

testBlueTicket

和

testOrangeTicket

视图嵌入到容器视图中

下面是一个简单的例子：

@interface FlipViewController ()

@property (strong, nonatomic) UIView *testBlueTicket;
@property (strong, nonatomic) UIView *testOrangeTicket;
@property (strong, nonatomic) UIView *containerView;

@end

@implementation FlipViewController

- (void)viewDidLoad {
    
    _containerView = [UIView new];
    _testBlueTicket = [UIView new];
    _testOrangeTicket = [UIView new];
    
    _containerView.translatesAutoresizingMaskIntoConstraints = NO;
    _testBlueTicket.translatesAutoresizingMaskIntoConstraints = NO;
    _testOrangeTicket.translatesAutoresizingMaskIntoConstraints = NO;
    
    _containerView.backgroundColor = [UIColor systemYellowColor];
    _testBlueTicket.backgroundColor = [UIColor systemBlueColor];
    _testOrangeTicket.backgroundColor = [UIColor systemOrangeColor];
    
    // respect safe area
    UILayoutGuide *g = [self.view safeAreaLayoutGuide];
    
    [_containerView addSubview:_testOrangeTicket];
    [_containerView addSubview:_testBlueTicket];
    
    [self.view addSubview:_containerView];
    
    [NSLayoutConstraint activateConstraints:@[
        
        [_containerView.widthAnchor constraintEqualToConstant:200.0],
        [_containerView.heightAnchor constraintEqualToConstant:260.0],
        [_containerView.centerXAnchor constraintEqualToAnchor:g.centerXAnchor],
        [_containerView.centerYAnchor constraintEqualToAnchor:g.centerYAnchor],
        
        [_testBlueTicket.widthAnchor constraintEqualToAnchor:_containerView.widthAnchor multiplier:1.0],
        [_testBlueTicket.heightAnchor constraintEqualToAnchor:_containerView.heightAnchor multiplier:1.0],
        [_testBlueTicket.centerXAnchor constraintEqualToAnchor:_containerView.centerXAnchor],
        [_testBlueTicket.centerYAnchor constraintEqualToAnchor:_containerView.centerYAnchor],
        
        [_testOrangeTicket.widthAnchor constraintEqualToAnchor:_containerView.widthAnchor multiplier:1.0],
        [_testOrangeTicket.heightAnchor constraintEqualToAnchor:_containerView.heightAnchor multiplier:1.0],
        [_testOrangeTicket.centerXAnchor constraintEqualToAnchor:_containerView.centerXAnchor],
        [_testOrangeTicket.centerYAnchor constraintEqualToAnchor:_containerView.centerYAnchor],
        
    ]];
    
    _testOrangeTicket.hidden = YES;
    
    UITapGestureRecognizer *t = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTap)];
    [self.view addGestureRecognizer:t];
}

- (void)didTap {
    
    UIView *fromView = self.testBlueTicket.isHidden ? self.testOrangeTicket : self.testBlueTicket;
    UIView *toView = self.testBlueTicket.isHidden ? self.testBlueTicket : self.testOrangeTicket;

    [UIView transitionFromView:fromView
                        toView:toView
                      duration:2
                       options:UIViewAnimationOptionTransitionFlipFromRight | UIViewAnimationOptionShowHideTransitionViews
                    completion:^(BOOL finished) {
        
    }];
    
}

@end

请注意，它使用的是

UIViewAnimationOptionShowHideTransitionViews

，因此“票证”视图保留在视图层次结构中

---

要想看得更清楚，请更改票证视图上的一些约束（例如宽度和/或高度约束上的

乘数：

）…然后，您将看到

.systemYellow

容器视图动画，其中嵌入了票证视图。

这听起来像是一个bug。您可以在问题中添加一个视频，告诉我们哪个视图是testOrangeTicket，或者发布一个我们可以尝试的最小可重复示例项目吗？（顺便说一句，您发布了Objective-C代码。对于Objective-C特定的问题，您可能不应该包含Swift标记。）
