IOS監聽屏幕狀態

一、定義兩個巨集

//鎖屏通知

#define NotificationOff CFSTR("com.apple.springboard.lockcomplete")

//解鎖通知

#define NotificationOn CFSTR("com.apple.springboard.hasBlankedScreen")

二、註冊屏幕監聽事件

    CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, ListeningScreenLockState, NotificationOff, NULL, CFNotificationSuspensionBehaviorDeliverImmediately);

    CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, ListeningScreenLockState, NotificationOn, NULL, CFNotificationSuspensionBehaviorDeliverImmediately);

三、屏幕監聽的事件

static void ListeningScreenLockState(CFNotificationCenterRef center,void* observer,CFStringRef name,const void* object,CFDictionaryRef userInfo)

{

    NSString* screenState = (__bridge NSString*)name;

    if ([screenState isEqualToString:(__bridge  NSString*)NotificationOff]) {

        NSLog(@"********鎖屏**********");

    } else {

        NSLog(@"********解鎖**********");

    }

}
