问题描述
如何在 swift 中获取屏幕上当前所有窗口的列表, ? (所有示例前面都有 import Cocoa
)
在 objective-c 成功运行以下代码:
CFArrayRef windowList = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID);
但是当我在 swift ):
let windowList = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kcGNullWindowID)
我得到一个错误告诉我有一个使用未解决的标识符'kcGNullWindowID'
。
I get an error telling me that I have an Use of unresolved identifier 'kcGNullWindowID'
.
在石英文档一段时间我已经得到:
After playing around with the help of the quartz documentation for a while I have gotten to:
let windowList = CGWindowListCopyWindowInfo(CGWindowListOption(kCGWindowListOptionOnScreenOnly), CGWindowListOption(0))
但它仍然不工作, {__ NSArrayM}
对象,我不知道如何访问。
But it still does not work as I am receiving a {__NSArrayM}
object, which I do not know how to access.
推荐答案
下面是Swift 2.0中的一个示例,它也展示了多个选项。
Here's an example in Swift 2.0, which also demonstrates multiple options.
let options = CGWindowListOption(arrayLiteral: CGWindowListOption.ExcludeDesktopElements, CGWindowListOption.OptionOnScreenOnly)
let windowListInfo = CGWindowListCopyWindowInfo(options, CGWindowID(0))
let infoList = windowListInfo as NSArray? as? [[String: AnyObject]]
