How to simulate mac media keys in cocoa

问题

I need simulate the pressing of the media/function keys on the mac keyboard. Everything from brightness to volume up/down.

Is this possible? And if so how? Ive read a bunch about how to trigger on their press, but not this.

If possible, id like the translucent icons to still come up on the screen as you change things.

Try this out in Swift:

// Simulate illumination up
let code = NX_KEYTYPE_ILLUMINATION_UP
let event1 = NSEvent.otherEvent(with: .systemDefined, location: NSPoint.zero, modifierFlags: NSEventModifierFlags(rawValue: 0xa00), timestamp: 0, windowNumber: 0, context: nil, subtype: 8, data1: (Int((code << 16 as Int32) | (0xa << 8 as Int32))), data2: -1)
event1?.cgEvent?.post(tap: .cghidEventTap)
let event2 = NSEvent.otherEvent(with: .systemDefined, location: NSPoint.zero, modifierFlags: NSEventModifierFlags(rawValue: 0xb00), timestamp: 0, windowNumber: 0, context: nil, subtype: 8, data1: (Int((code << 16 as Int32) | (0xb << 8 as Int32))), data2: -1)
event2?.cgEvent?.post(tap: .cghidEventTap)



// Simulate illumination down
let code = NX_KEYTYPE_ILLUMINATION_DOWN
let event1 = NSEvent.otherEvent(with: .systemDefined, location: NSPoint.zero, modifierFlags: NSEventModifierFlags(rawValue: 0xa00), timestamp: 0, windowNumber: 0, context: nil, subtype: 8, data1: (Int((code << 16 as Int32) | (0xa << 8 as Int32))), data2: -1)
event1?.cgEvent?.post(tap: .cghidEventTap)
let event2 = NSEvent.otherEvent(with: .systemDefined, location: NSPoint.zero, modifierFlags: NSEventModifierFlags(rawValue: 0xb00), timestamp: 0, windowNumber: 0, context: nil, subtype: 8, data1: (Int((code << 16 as Int32) | (0xb << 8 as Int32))), data2: -1)
event2?.cgEvent?.post(tap: .cghidEventTap)
