一、定义两个宏
//锁屏通知
#define NotificationOff CFSTR("com.apple.springboard.lockcomplete")
//解锁通知
#define NotificationOn CFSTR("com.apple.springboard.hasBlankedScreen")
二、注册屏幕监听事件
CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, ListeningScreenLockState, NotificationOff, NULL, CFNotificationSuspensionBehaviorDeliverImmediately);
CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, ListeningScreenLockState, NotificationOn, NULL, CFNotificationSuspensionBehaviorDeliverImmediately);
三、屏幕监听的事件
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(@"********锁屏**********");
} else {
NSLog(@"********解锁**********");
}
}
