如何暂停 UIImageView 动画

How to pause a UIImageView animation(如何暂停 UIImageView 动画)

问题描述

我有一个正在使用 UIImageView 显示的动画:

I have an animation that I'm displaying using a UIImageView:

imageView.animationImages = myImages;
imageView.animationDuration = 3;
[imageView startAnimating];

我知道我可以使用 stopAnimating 来停止它，但我想要的是能够暂停它.原因是当您调用停止时，您的动画图像都不会显示，而我希望在我按下按钮时显示的最后一个动画图像保持不变.

I know I can stop it using stopAnimating, but what I want is to be able to pause it. The reason is that when you call stop, none of your animation images are displayed, whereas I would like the last one that is up at the time when I hit a button to stay up.

我尝试将持续时间设置为更大的数字，但这也会导致所有图像消失.必须有一个非常基本的方法来做到这一点?

I have tried setting the duration to a much larger number, but that causes all the images to disappear as well. There must be a really basic way to do this?

推荐答案

嗯...因为似乎没有人知道我猜这是不可能的.

Hmmm...since no one seems to know I guess it's not possible.

我继续编写了自己的 UIView，带有 UIImageView subview，它使用 NSTimer在图像之间切换.这样做的好处是我可以在闲暇时暂停和恢复计时器，而且性能似乎不是问题.

I went ahead and wrote my own UIView, with a UIImageView subview, that uses an NSTimer to switch between images. The advantage of this is that I can pause and resume the timer at my leisure, and performance doesn't seem to be an issue.
