淡出动画（UIViewAnimation） [英] Fade Animation (UIViewAnimation)

问题描述

在这一点上，我用简单的视图切换工作，现在我与动画制作工作，而切换以x code意见。然而，我的知识是没有的话题广泛，我花了大约一个小时研究发布之前这个问题，所以我都试过了，

At this point, I am working with simple view switching, and now I'm working with animation while switching views in xcode. However, my knowledge is not extensive on the topic, and I have spent about an hour researching this question before posting, so I have tried,

所有我想要做的就是简单地淡出到下一个视图。我不知道是否有它的动画，但是我做的是让app黑渐变在某一方向练习。但是，如果有更好的动画，你可以建议，请这样做。谢谢！

All I want to do is simply fade to the next view. I don't know if there is an animation for it, but what I am doing is making the app fade to black on a certain orientation for practice. However, if there is a better animation that you could suggest, please do so. Thanks!

推荐答案

如果这是你的问题的症结所在所有我想做的只是淡出到下一个视图。那么这是与形式上的过渡风格很容易办到。假设你有一个名为候补一个的UIViewController 子类要转换此示例。

If this is the crux of your question "All I want to do is simply fade to the next view." Then this is achieved very easily with the modal transition style. Assume for this example you have a UIViewController subclass named Alternate to which you want to transition.

Alternate *alt = [[Alternate alloc] initWithNibName:nil bundle:nil];
alt.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:alt animated:YES];
