如何模拟按下键盘按钮？

我尝试过：

let src = CGEventSource(stateID: CGEventSourceStateID.hidSystemState)

let cmdd = CGEvent(keyboardEventSource: src, virtualKey: 0x38, keyDown: true)
let cmdu = CGEvent(keyboardEventSource: src, virtualKey: 0x38, keyDown: false)
let spcd = CGEvent(keyboardEventSource: src, virtualKey: 0x31, keyDown: true)
let spcu = CGEvent(keyboardEventSource: src, virtualKey: 0x31, keyDown: false)

spcd?.flags = CGEventFlags.maskCommand;

let loc = CGEventTapLocation.cghidEventTap

cmdd?.post(tap: loc)
spcd?.post(tap: loc)
spcu?.post(tap: loc)
cmdu?.post(tap: loc)

并且：

let controlKeyDownEvent = CGEvent(keyboardEventSource: nil, virtualKey: CGKeyCode(kVK_Control), keyDown: true)
   controlKeyDownEvent?.flags = CGEventFlags.maskCommand
   controlKeyDownEvent?.post(tap: CGEventTapLocation.cghidEventTap)

但是我遇到了错误：

Use of unresolved identifier 'CGEvent' 
Use of unresolved identifier 'CGKeyCode' 
Use of unresolved identifier 'kVK_Control'

等

如何使用此代码？

要连接哪种框架？

或者我该怎么做？

Answer 1

CGEventSourceRef only exists on macOS。

您可能还有其他选择可以尝试。 Check out Olaf's answer here。

否则，您需要退后一步，弄清楚如何 else 在不涉及键盘的情况下测试UI背后的代码。
