iOS_获取&区分iOS锁屏与Home事件

来源：互联网发布：五大联赛数据编辑：程序博客网时间：2024/05/19 16:27

今天在研究获取是否锁屏状态，没找到方法。有找到的说要越狱，没越狱的方法又只能获取到响应通知，不能识别是锁还是解。无意间看到这么个文章，测试了一下真机可以运行就收藏留着后面备用吧！（测试环境：iPhone5s）

上面那个只能响应锁屏、点击home键进入后台。

以下是自己综合网上的写出来的方法。

通知方式判断解锁/锁屏：目前我只能在运行当前demo的时候响应通知，不能获取到状态，初步考虑是认为加入bool判断（因为，我觉得锁屏、解锁跟开关值是一个意思）。废话有点多，先上代码：

//这段写在：- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions    CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, updateEnabled, CFSTR("com.apple.iokit.hid.displayStatus"), NULL, CFNotificationSuspensionBehaviorDeliverImmediately);

//这段写在：AppDelegate 下static void updateEnabled(CFNotificationCenterRef center, void* observer, CFStringRef name, const void* object, CFDictionaryRef userInfo) {    NSLog(@"锁屏/解锁");}
