iOS锁屏问题解决方式

    第一种方式可以写函数判断

 

int hasBlankedScreen;

       

static void setScreenStateCb()

{

#if 0//是否锁屏

    uint64_t locked;

    __block int token = 0;

    notify_register_dispatch("com.apple.springboard.lockstate",&token,dispatch_get_main_queue(),^(int t){

        

    });

    notify_get_state(token, &locked);

    NSLog(@"是否锁着%d",(int)locked);

#endif

#if 1 //是否亮屏

    uint64_t locked;

    __block int token = 0;

    notify_register_dispatch("com.apple.springboard.hasBlankedScreen",&token,dispatch_get_main_queue(),^(int t){

        

    });

    notify_get_state(token, &locked);

    NSLog(@"是否亮屏%d",(int)locked);

    hasBlankedScreen = (int)locked;

   

#endif

}

第二种方式用系统的通知来处理

   //监听锁屏

 CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), //center

                                    NULL, // observer

                                    displayStatusChanged, // callback

                                    CFSTR("com.apple.springboard.hasBlankedScreen"), // event name

                                    NULL, // object

                                    CFNotificationSuspensionBehaviorDeliverImmediately);

//method

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

{

    // the "com.apple.springboard.lockcomplete" notification will always come after the "com.apple.springboard.lockstate" notification

    CFStringRef nameCFString = (CFStringRef)name;

    NSString *lockState = (__bridge NSString*)nameCFString;

    NSLog(@"Darwin notification NAME = %@",name);

    

    if([lockState isEqualToString:@"com.apple.springboard.hasBlankedScreen"])

    {

       

        

        

        UIApplication *app=[UIApplication sharedApplication];

        if (app.applicationState==UIApplicationStateActive) {

             [[NSNotificationCenter defaultCenter]postNotificationName:@"isPlay" object:nil userInfo:[NSNumber numberWithInteger:1]];

        }else

        {

             [[NSNotificationCenter defaultCenter]postNotificationName:@"isPlay" object:nil userInfo:[NSNumber numberWithInteger:0]];

        }

        //Logic to disable the GPS

    }

}
