當Mac從睡夢中恢復時會發生什麼事件？

Question

我正在開發Mac上的Xcode應用程序，並希望知道當mac從睡眠中恢復時觸發的事件。 AmaweFromNib似乎沒有工作。

謝謝！

Answer 1

只是覺得：

- (void) receiveWakeNote: (NSNotification*) note 
{ 
    NSLog(@"receiveSleepNote: %@", [note name]); 
} 

- (void) fileNotifications 
{ 
    //These notifications are filed on NSWorkspace's notification center, not the default 
    // notification center. You will not receive sleep/wake notifications if you file 
    //with the default notification center. 
    [[[NSWorkspace sharedWorkspace] notificationCenter] addObserver: self 
                  selector: @selector(receiveWakeNote:) 
                   name: NSWorkspaceDidWakeNotification object: NULL]; 
} 

Answer 2

您可以使用IORegisterForSystemPower()。

連接呼叫者根電源域的IOService，用於接收系統休眠喚醒&通知的目的 。 不提供系統關閉和重新啓動通知。

io_connect_t IORegisterForSystemPower (
    void *refcon, 
    IONotificationPortRef *thePortRef, 
    IOServiceInterestCallback callback, 
    io_object_t *notifier) ;

爲SWIFT 3：

func onWakeNote(note: NSNotification) { 
    print("Received wake note: \(note.name)") 
} 

func onSleepNote(note: NSNotification) { 
    print("Received sleep note: \(note.name)") 
} 

func fileNotifications() { 
    NSWorkspace.shared().notificationCenter.addObserver(
     self, selector: #selector(onWakeNote(note:)), 
     name: Notification.Name.NSWorkspaceDidWake, object: nil) 

    NSWorkspace.shared().notificationCenter.addObserver(
     self, selector: #selector(onSleepNote(note:)), 
     name: Notification.Name.NSWorkspaceWillSleep, object: nil) 
}
