如何在可可中模拟mac媒体键

Question

我需要模拟按下 mac 键盘上的媒体/功能键。从亮度到音量调高/调低，应有尽有。

这可能吗？如果是这样怎么办？我读过很多关于如何在他们的媒体上触发的文章，但不是这个。

如果可能，当您更改内容时，id 喜欢半透明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)
