动画的UIImageView在落后第一次运行 [英] UIImageView animations lag at first run

问题描述

我有一系列的，在我的应用程序中播放的图像（这只是得到了一个视图/的ViewController）。每当我运行应用程序，我第一次播放动画，它会有点滞后首次动画被告知要发挥。

I have a series of images that play in my application (it's only got one view/viewcontroller). Whenever I run the app, the first time I play an animation, it will lag a bit the first time the animation is told to play.

我通过不同的方法（例如，animateJump），这是负责加载正确的帧，然后播放动画运行我的动画。动画结束后，我（据说）释放从UIImageView的动画，把后面一个框架中显示。 （我说据说，因为如果动画只落后他们跑的第一次，他们真的是从内存释放？）

I run my animations via different methods (e.g. "animateJump") which are responsible for loading the correct frames, then playing the animation. After the animation finishes, I (supposedly) release the animation from the UIImageView, putting back a single frame to display. (I say supposedly because if the animations are only lagging the first time they run, are they really being release from memory?)

那么，有没有一个简单的解决这个？我有大约100动画我去来回的帧。如果我只是加载它们都到内存在应用程序的启动？你会怎么做？

So is there a simple fix to this? I have about 100 frames of animation I go back and forth through. Should I just load them all into memory at the application's start up? What would you do?

推荐答案

如果你已经有了一段时间加载，我D可能在使用它，而它隐藏/非可视运行动画。

If you've already got a period of loading, I"d probably use it to run the animation whilst it's hidden/non-viewable.
