相关宏定义：

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

#define NotificationChange CFSTR("com.apple.springboard.lockstate")

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

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

[self addScreenStatusObserve]; // 视频锁屏监听

应用程序自身代理的方法直接写需求即可。方法如下：

／／进入前台

1. - (void)applicationWillEnterForeground:(UIApplication *)application

／／非活动状态，会在后台保持一段时间，再将程序杀死

2. - (void)applicationDidBecomeActive:(UIApplication *)application

return YES;

}

- (void)addScreenStatusObserve {

CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, screenLockStateChanged, NotificationLock, NULL, CFNotificationSuspensionBehaviorDeliverImmediately);

CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, screenLockStateChanged, NotificationChange, NULL, CFNotificationSuspensionBehaviorDeliverImmediately);

}

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

{

NSString* lockstate = (__bridge NSString*)name;

if ([lockstate isEqualToString:(__bridge NSString*)NotificationLock]) {

NSLog(@"locked.");

} else if ([lockstate isEqualToString:(__bridge NSString*)NotificationChange]) {

NSLog(@"lock state changed.");

}
