连续动画 - Watchkit [英] Consecutive Animations - Watchkit

问题描述

我希望为 Apple Watch 应用提供各种动画.我正在使用一系列图像，动画方法是 startAnimatingWithImagesInRange().每当我有连续的动画指令时，只会执行代码中的最后一个.代码如下:

I'm looking to have a variety of animations for an apple watch app. I'm using a series of images and the method of animation is startAnimatingWithImagesInRange(). Any time I have consecutive animation instructions, only the last one in the code executes. Code looks like:

myImage.setImageNamed("testImage")

myImage.startAnimatingWithImagesInRange(NSRange(location: 0, length: 90), duration: 3, repeatCount: 1)

myImage.startAnimatingWithImagesInRange(NSRange(location: 90, length: 180), duration: 3, repeatCount: 1)

在上面的代码中，只会播放第二个动画.我什至尝试将它们放在单独的函数中，所以我会单独调用每个函数，但它仍然只会播放我代码中的最后一个动画.我对此很陌生，所以我确信有更好的方法，但经过数小时的研究，我一直无法想出解决方案或在网上找到解决方案.

In the above code, only the second animation would play. I even tried putting them in separate functions, so I would be calling each function individually, but it still will only play the last animation in my code. I'm fairly new to this so I'm sure there is a better way but after hours and hours of research I haven't been able to come up with a solution or find one online.

推荐答案

手表不会为你排队动画，所以使用一个延迟等于第一个动画持续时间的 NSTimer 并在第二个动画结束后开始定时器触发.

The watch won't queue up animations for you, so use an NSTimer with a delay equal to the duration of the first animation and start the second animation once the timer fires.
