Question

有没有人有任何想法，这不再是iOS8中的自定义翻转动画，而是在iOS7中。

在iOS8中，我只是看到没有动画的视图，但是当视图被取消时我确实得到了自定义翻转过渡。它就像忘记动画一样，但是当它被解雇时它会记得。

任何帮助都会受到赞赏，这让我疯狂。

- (void) animateTransition:(id <UIViewControllerContextTransitioning>)transitionContext {

    UIView *containerView = [transitionContext containerView];

    UIViewController *fromVC = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
    [containerView addSubview:fromVC.view];

    UIViewController *toVC = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
    [containerView addSubview:toVC.view];

    UIViewAnimationOptions animationOption = ([toVC.presentedViewController isEqual:fromVC])?UIViewAnimationOptionTransitionFlipFromLeft:UIViewAnimationOptionTransitionFlipFromRight;

    if ([toVC class] == [ClockViewController class]) {

        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];

    }

    [UIView transitionFromView:fromVC.view
                        toView:toVC.view
                      duration:0.7f
                       options:animationOption
                    completion:^(BOOL finished){
                        [transitionContext completeTransition:YES];
                    }];

}

如果有人遇到同样的问题，请找出解决我问题的方法。

添加了[CATransaction commit];在过渡之前，它现在有效。

（void）animateTransition：（id）transitionContext {

UIView * containerView = [transitionContext containerView];

UIViewController * fromVC = [transitionContext viewControllerForKey：UITransitionContextFromViewControllerKey]; [containerView addSubview：fromVC.view];

UIViewController * toVC = [transitionContext viewControllerForKey：UITransitionContextToViewControllerKey]; [containerView addSubview：toVC.view];

UIViewAnimationOptions animationOption =（[toVC.presentedViewController isEqual：fromVC]）？UIViewAnimationOptionTransitionFlipFromLeft：UIViewAnimationOptionTransitionFlipFromRight;

[CATransaction commit];

[UIView transitionFromView：fromVC.view toView：toVC.view 持续时间：0.7F 选项：animationOption 完成：^（BOOL完成）{ [transitionContext completeTransition：YES]; }];

}
