Question

我有一个非常奇怪的问题：

我的后台服务正试图通过使用NSEvents监控NSEvent.addGlobalMonitorForEvents(matching: mask, handler: handler)来检测用户是否处于空闲状态。到目前为止一切顺利，我能够毫无问题地获得mouseMoved，leftMouseDown或keyDown等鼠标和键盘通知。

但是我注意到，我没有收到手势的事件，比如用3个手指轻扫以显示任务控制。目前我将所有NSEventMask值都放入matching:，因为我想要监控任何用户活动。有NSEventMask.any价值，但如果我使用它，我就不会有任何事件......

这是我的代码：

EventMonitor-包装

public class EventMonitor {
    private var monitor: Any?
    private let mask: NSEventMask
    private let handler: (NSEvent?) -> ()

    public init(mask: NSEventMask, handler: @escaping (NSEvent?) -> ()) {
        self.mask = mask
        self.handler = handler
    }

    deinit {
        stop()
    }

    public func start() {
        self.monitor = NSEvent.addGlobalMonitorForEvents(matching: mask, handler: handler)
    }

    public func stop() {
        if self.monitor != nil {
            NSEvent.removeMonitor(self.monitor!)
            self.monitor = nil
        }
    }
}

跟踪-服务：

private static let inactivityEvents: NSEventMask = [NSEventMask.leftMouseDown, NSEventMask.leftMouseUp, NSEventMask.rightMouseDown, NSEventMask.rightMouseUp, NSEventMask.mouseMoved, NSEventMask.leftMouseDragged, NSEventMask.rightMouseDragged, NSEventMask.mouseEntered, NSEventMask.mouseExited, NSEventMask.keyDown, NSEventMask.keyUp, NSEventMask.flagsChanged, NSEventMask.appKitDefined, NSEventMask.systemDefined, NSEventMask.applicationDefined, NSEventMask.periodic, NSEventMask.cursorUpdate, NSEventMask.scrollWheel, NSEventMask.tabletPoint, NSEventMask.tabletProximity, NSEventMask.otherMouseDown, NSEventMask.otherMouseUp, NSEventMask.otherMouseDragged, NSEventMask.gesture, NSEventMask.magnify, NSEventMask.swipe, NSEventMask.rotate, NSEventMask.beginGesture, NSEventMask.endGesture, NSEventMask.smartMagnify, NSEventMask.pressure]

init() {
    self.eventMonitor = EventMonitor(mask: TrackingService.inactivityEvents) {event in
        print("event detected: \(event)")
        if self.isTracking() {
            self.idleTimer = Timer.scheduledTimer(timeInterval: 2 * 60, target: self, selector: #selector(TimeTrackingService.inactivityDetected(_:)), userInfo: nil, repeats: false)
        } else {
            self.unpauseTracking()
        }
    }
}

func startService() {
    //start service will be called from a background queue
    DispatchQueue.main.async {
        self.eventMonitor?.start()
    }
}

我做错了什么？ NSEventMask.any有什么问题？任何建议将不胜感激。

使用addGlobalMonitorForEvents丢失手势事件来监视NSEvents
