如何暂停UIImageView动画 [英] How to pause a UIImageView animation

问题描述

我有一个动画，我使用UIImageView显示：

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。原因是当你调用stop，你的动画图像都不会显示，而我想要的最后一个在我按下按钮时保持up。

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.

我已经尝试将持续时间设置为更大的数字，但是这会导致所有的图像也消失。

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...因为没有人知道我猜这不是可能。

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

我写了我自己的 UIView ，带有 UIImageView subview ，它使用 NSTimer 在图像之间切换。这样做的优点是，我可以暂停和恢复计时器在我的闲暇，性能似乎不是一个问题。

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.
