问题
I've seen this question asked a couple of times but nobody has answered it - in fact it might be impossible, but I was wondering if there was a way to prevent the screen from going black when the proximityState changes on the iPhone?
I have implemented a method to do something when the proximity state changes, but the screen flickers to black and I want to avoid that. Here is my code:
[nc addObserver:self selector:@selector(proximityChanged:) name:UIDeviceProximityStateDidChangeNotification object:d];
- (void)proximityChanged:(NSNotification *)note {
if ([[note object] proximityState] == 1) {
// Do something once the face is close
// This is where it goes to black
} else {
// Do something once the face pulls away
}
}

Sadly, the current public APIs do not allow you to do this. You might want to file an enhancement request via the Apple Bug Reporter: http://developer.apple.com/bugreporter/
