为大量“LED”设置动画的策略- 线程？，UIView 动画？ NS操作？（iPhone）

我必须制作一些包含 72 个 LED 灯的不同视图。我构建了一个 LED 类，这样我就可以循环 LED 并将它们设置为不同的颜色（绿色、红色、橙色、蓝色、无等）。然后 LED 会加载适当的 .png。

这工作正常，我循环 LED 并设置它们。现在我知道，有时他们不仅需要打开/关闭改变颜色，而且还需要稍微延迟打开。就像均衡器一样。

我有一个包含 72 个 LED 的 5-10 个视图，我希望以最小的内存/CPU 压力来实现上述目标。

for(LED *l in self.ledArray) {

    [l display:Green];
}

我只是如上所示循环，LED 内部有一个执行正确逻辑的 switch case。如果这是实际的 LED 和微控制器，我会在循环中使用 sleep(100) 或类似的东西，但由于显而易见的原因，我真的很想避免类似的东西。

我认为执行 performOnThread withDelay 确实会很消耗，因此 UIView 动画 更改 alpha 和 NSOperation 对于一个小功能来说也会有很大的提升。

有没有一种既有效又聪明的方法来解决这个问题？

感谢您提供的任何灵感:)

I have to do some different views containing 72 LED lights. I built an LED Class so I can loop through the LED's and set them to different colors (Green, Red, Orange, Blue None etc.).
The LED then loads the appropriate .png.

This works fine, I loop over the LED's and set them.
Now I know that at some time they will need to not just turn on/off change color, but will have to turn on with a small delay. Like an equalizer.

I have a 5-10 views containing the 72 LED's and I would like to achieve the above with the minimum amount of memory/CPU strain.

for(LED *l in self.ledArray) {

    [l display:Green];
}

I simply loop as shown above and inside the LED is a switch case that does the correct logic.
If this were actual LED's and a microController I would use sleep(100) or similar in the loop, but I would really like to avoid stuff like that for obvious reasons.

I was thinking that doing a performOnThread withDelay would really be consuming, so would UIView animation changing the alpha and NSOperation would also be a lot of lifting for a small feature.

Is there a both efficient and clever way to go around this?

Thanks for any inspiration given:)
