Animated GIF alternative for iOS
提问by Steve
"Back in the day" animated GIFs were ubiquitous online.
“回到过去”动画 GIF 在网上无处不在。
They were simple to use - just pop em' in wherever you want an animated image.
它们易于使用 - 只需在您想要动画图像的任何地方弹出它们即可。
I'd like to display an animated image within an iOS application (for example, a graphic illustrating a letter being opened from an envelope).
我想在 iOS 应用程序中显示动画图像（例如，说明从信封中打开一封信的图形）。
But, I'm not sure how to go about this.
但是，我不知道该怎么做。
Obviously I don't want to use an animated GIF.
显然我不想使用动画 GIF。
A video of some sort seems like it might be the preferred solution. But, what about transparency? Also, what about the retina display?
某种视频似乎是首选的解决方案。但是，透明度呢？另外，视网膜显示器怎么样？
Thanks.
谢谢。
