鎖屏和息屏監(jiān)聽

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
   //傳感器(紅外感應(yīng))打開
    [[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
    //設(shè)置監(jiān)聽
    [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(sensorStateChange:)
                                                     name:UIDeviceProximityStateDidChangeNotification
                                                   object:nil];
    
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(LOCK_SCREEN:)
                                                 name:UIApplicationProtectedDataWillBecomeUnavailable
                                               object:nil];
     
     [[NSNotificationCenter defaultCenter] addObserver:self
                                              selector:@selector(UN_LOCK_SCREEN:)
                                                  name:UIApplicationProtectedDataDidBecomeAvailable
                                                object:nil];
    
}
- (void)LOCK_SCREEN:(NSNotificationCenter *)notification {
    NSLog(@">>>鎖屏");
}
- (void)UN_LOCK_SCREEN:(NSNotificationCenter *)notification {
    NSLog(@">>>解除鎖屏");
}
- (void)sensorStateChange:(NSNotificationCenter *)notification {
    if ([[UIDevice currentDevice] proximityState] == YES) {
        NSLog(@">>>屏幕熄滅");
    }else{
        NSLog(@">>>屏幕亮起");
    }
}

一些說明
如下方法是監(jiān)聽 傳感器(紅外感應(yīng)) YES開啟 NO關(guān)閉
[[UIDevice currentDevice] setProximityMonitoringEnabled:YES];

這種息屏監(jiān)聽是監(jiān)聽的傳感器，手機(jī)放置不動(dòng)直至黑屏，實(shí)際上是手機(jī)鎖屏，注意甄別。

iOS App不息屏設(shè)置

[[UIApplication sharedApplication] setIdleTimerDisabled:YES];
