Hi
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:)
