ios - 是否可以区分锁定设备和将应用程序发送到 iOS 10 和 swift 的后台？

Question

我found answer对于我的问题的 iOS 5，但是 iOS10 呢？可以在 Swift3 上实现吗？对于 iOS 5:

// Pressing the home button
Will resign active.
Did enter background.
// Tapping app icon on Springboard
Will enter foreground.
Did become active.

// Pressing the lock button
Will resign active.
Did enter background.
// Unlocking the device
Will enter foreground.
Did become active.

是的，当屏幕锁定时，名为 com.apple.springboard.lockcomplete 的通知会被调用。

    CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(),
                                    nil, { (_, observer, name, _, _) in
                                            print("Locked") 
                                         },
                                    "com.apple.springboard.lockcomplete" as CFString!,
                                    nil, deliverImmediately)

要检测背景/前景模式，您需要收听通知。

 NotificationCenter.default.addObserver(self, selector:#selector(handleForegroundMode), name: NSNotification.Name.UIApplicationDidBecomeActive, object: nil)
 NotificationCenter.default.addObserver(self, selector:#selector(handleBackgroundMode), name: NSNotification.Name.UIApplicationDidEnterBackground, object: nil)
