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?
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.
