如何在cocoa中模拟mac媒体密钥

Question

我需要模拟按下Mac键盘上的媒体/功能键。从亮度到音量上/下的一切。

这可能吗？如果是这样怎么样？我读了一堆关于如何触发他们的新闻，但不是这个。

如果可能的话，当你改变东西时，id就像半透明的图标仍会出现在屏幕上。

在Swift中试试这个：

// 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)
