我试图有一个处理程序在我的Mac OS X应用程序中用Swift编写的全局(系统范围)热键组合，但我只是无法找到适当的文档。我读过，我不得不在一些遗留的Carbon API为它，是没有更好的方法？你能给我一些概念证明Swift代码吗？提前致谢！
自从Swift 2.0以来，你现在可以传递一个函数指针到C API。

gMyHotKeyID.signature = OSType("swat".fourCharCodeValue)
gMyHotKeyID.id = UInt32(keyCode)
var eventType = EventTypeSpec()
eventType.eventClass = OSType(kEventClassKeyboard)
eventType.eventKind = OSType(kEventHotKeyPressed)
// Install handler.
InstallEventHandler(GetApplicationEventTarget(),{(nextHanlder,theEvent,userData) -> OSStatus in
var hkCom = EventHotKeyID()
GetEventParameter(theEvent,EventParamName(kEventParamDirectObject),EventParamType(typeEventHotKeyID),nil,sizeof(EventHotKeyID),&hkCom)
/// Check that hkCom in indeed your hotkey ID and handle it.
},1,&eventType,nil)
// Register hotkey.
let status = RegisterEventHotKey(UInt32(keyCode),UInt32(modifierKeys),gMyHotKeyID,GetApplicationEventTarget(),&hotKeyRef)
