Here’s my problem : I have an app which contains something like 15 VU meters, and for now, every VU meter has his own timer, which is 15 timers only for them. Every TimerCallback, I do a checking to know if I need to repaint() them, one by one, and I think it’s pretty optimized there (the condition of the potential repainting)
I’ve set my VU meters to opaque to avoid 15 repainting of the parent component, and my only “problem” for optimisation is now the timers, because my app uses up to 120% of the CPU of my iPad 4 WiFi, which seems a lot to me, but maybe it’s “normal”
So, is there a way to actually make all the VU meters to use the same timer, and each one of the VU meter uses his own timerCallback()
Thanks a lot !
