Question

我正在创建一个显示监视器iBeacon区域的应用程序，这意味着当设备被锁定并且在信标范围内时，我的应用程序的图标会显示在左下角的锁定屏幕上。

有什么方法可以检测我的应用是通过此锁定屏幕图标启动，并运行一些代码？

Answer 1

当图标出现时，表示已输入信标区域。首次出现图标时，系统会调用CLLocationManager代理的didEnterRegion方法。

您可以在其中放置自定义代码以设置指示图标出现的标记。

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
    _iconShown = YES;
}

然后，当您的应用程序到达前台时，您可以检查此标志以查看它是否已设置，并执行您的自定义逻辑：

- (void)applicationWillEnterForeground:(UIApplication *)application {
    if (_iconShown) {
        _iconShown = NO;

        // Put custom logic here for launching from the icon
    }
}

嗯，有另一种方法，你可以处理它，只需创建一个变量self.backgroundedToLockScreen，如：

- (void)applicationWillEnterForeground:(UIApplication *)application {
    if (self.backgroundedToLockScreen) {
        ... // app was backgrounded to lock screen
    } else {
        ... // app was backgrounded on purpose by tapping the home button or switching apps.
    }
    self.backgroundedToLockScreen = NO;
}

和

- (void)applicationWillEnterForeground:(UIApplication *)application {
    UIApplicationState state = [[UIApplication sharedApplication] applicationState];
    if (UIApplicationStateInactive == state ||  // detect if coming from locked screen (iOS 6)
        self.backgroundedToLockScreen)          // detect if backgrounded to the locked screen (iOS 7)
    {
        ... // app is coming from or was backgrounded to lock screen
    } else {
        ... // app was backgrounded on purpose by tapping the home button or switching apps
    }
    self.backgroundedToLockScreen = NO;
}

希望这对你有用。
