使用Swift复制选定的文本 [英] Copy Selected Text with Swift
本文介绍了使用Swift复制选定的文本的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在OS X中编写一个弹出菜单栏应用程序.
I am writing a popover menu bar app in OS X.
目标是将当前处于活动状态的应用程序(不是我的弹出窗口)的选定文本复制到我的应用程序中,以便我可以将其用作字符串.
The goal is to copy the selected text of the currently active application (not my popover) into my app so I can use it as a String.
推荐答案
想通了!
注意:您必须延迟粘贴功能.copyText()需要一些时间才能写入粘贴板.
NOTE: You have to delay the paste function. copyText() needs time to write to the pasteboard.
func copyText() {
// Clear pasteboard
pasteBoard.clearContents()
let src = CGEventSourceCreate(CGEventSourceStateID.HIDSystemState)
//let cmdd = CGEventCreateKeyboardEvent(src, 0x37, true)
let cmdu = CGEventCreateKeyboardEvent(src, 0x37, false)
let c_down = CGEventCreateKeyboardEvent(src, 0x08, true)
let c_up = CGEventCreateKeyboardEvent(src, 0x08, false)
// Set Flags
CGEventSetFlags(c_down, CGEventFlags.MaskCommand)
CGEventSetFlags(c_up, CGEventFlags.MaskCommand)
let loc = CGEventTapLocation.CGHIDEventTap
//CGEventPost(loc, cmdd)
CGEventPost(loc, c_down)
CGEventPost(loc, c_up)
CGEventPost(loc, cmdu)
}
func paste() -> String {
let lengthOfPasteboard = pasteBoard.pasteboardItems!.count
print(lengthOfPasteboard)
var theText = ""
if lengthOfPasteboard > 0 {
theText = pasteBoard.pasteboardItems![0].stringForType("public.utf8-plain-text")!
} else {
theText = "Nothing Coppied"
}
//print(theText)
return theText
}
我从AppDelegate.swift而不是ViewController调用它.这样一来,它有望在我的弹出窗口成为活动/焦点窗口之前复制文本.
I'm calling this from AppDelegate.swift, not the ViewController. So that it will hopefully copy the text before my popover becomes the active/focused window.
