iPhone 近距离监控
我有这个应用程序可以全天监控您。当您将设备放入口袋时，屏幕将使用接近传感器关闭以节省电池。我的问题是它仍然没有节省足够的电池，所以我试图检测接近状态何时发生变化，接近监控将禁用。这给我带来了更多问题，因为接近监控将停止，但直到您揭开传感器为止。 这是我的代码。
- (void)viewDidLoad{
[super viewDidLoad];
[[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
[[UIDevice currentDevice] proximityState];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(proximityStateDidChange) name:UIDeviceProximityStateDidChangeNotification object:nil];
[self curTime];
}
-(void)proximityStateDidChange{
[[UIDevice currentDevice] setProximityMonitoringEnabled:NO];
NSLog(@"Disabled");
}
I have this app that monitors you through out the day. When you place your device in your pocket, the screen will turn off using the proximity sensor to conserve battery. My problem is it still is not conserving enough battery so I am trying to detect when the proximity state changes the proximity monitoring will disable. This brings me more problems because the proximity monitoring will stop but not until you uncover the sensor.
Here is my Code.
- (void)viewDidLoad{
[super viewDidLoad];
[[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
[[UIDevice currentDevice] proximityState];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(proximityStateDidChange) name:UIDeviceProximityStateDidChangeNotification object:nil];
[self curTime];
}
-(void)proximityStateDidChange{
[[UIDevice currentDevice] setProximityMonitoringEnabled:NO];
NSLog(@"Disabled");
}
