How to wake up ios from my app?

Question

In my game, the sprites blink when iOS goes into idle. To fix this issue, I set idle timer disabled, but the app can still get idle in some scenarios, for instance, the app get sleep and then switch back by users.

Is there any way I can wake up ios proactively with some API?

Answer 1

There is no way of doing it other than:

[UIApplication sharedApplication].idleTimerDisabled = YES;

Only the user can control when your app is sent to background / foreground / sleep.
