如何提高拉基UIView动画的性能-howtoimprovetheperformanceofalaggyUIViewanimation

The problem isn't really in how you call the animation, but in the drawing code you have for the views. If you optimize the logic and time required for rendering the views in those controllers, I guarantee you will see better performance in the animations between them.

问题不在于如何调用动画，而在于视图的绘图代码。如果您优化了在这些控制器中呈现视图所需的逻辑和时间，我保证您将在它们之间的动画中看到更好的性能。

You could try turning on the cache argument that you have currently set to NO to see if that helps in the short term, but it really is a bandaid, not a cure.

您可以尝试打开缓存参数，您目前设置为NO，看看这在短期内是否有用，但它实际上是一个绷带，而不是一个治愈方法。

Also, with a frame rate of 60fps at best, a .5 second animation is going to have only 30 frames to work with at most. If you increase the animation duration a little, it will appear to be smoother once you have the view rendering optimized.

同时，帧率为60fps最多，一个。5秒动画最多只能有30帧。如果您稍微增加动画持续时间，那么在视图呈现得到优化之后，它将看起来更加平滑。
