iOS动画性能(iOS Animation Performance)

 我有一个带有许多动画“怪物”的游戏。 动画制作每个怪物约20张图像。 所以我使用UIImageView设置了animationImages: . 
 
 问题是有时屏幕上会有很多怪物（总共多达110个，最多10个不同）。 因此，当所有这些都同时出现在屏幕上时 - 我看到了动画问题（非常低的fps）。 
 
 拜托，您能给我一些建议 - 我该如何解决这个问题？ 

I have a game with a number of animated "monsters". The animation is made with ~20 png images for each monster. So I use UIImageView with setted animationImages:.
 
The problem is that sometimes there can be a lot of monsters on the screen (up to 110 in total and up to 10 different). So when all of them are on the screen at the same time - I see animation problems (very low fps).
 
Please, can you give me some advice - how can I solve this problem?
