如何通过 swift3 从标题中获取 window id

Question

如何从标题中得到CGWindowID？

我以为我可以通过这个代码得到标题列表

let options = CGWindowListOption(arrayLiteral: CGWindowListOption.excludeDesktopElements, CGWindowListOption.optionOnScreenOnly)
let windowListInfo = CGWindowListCopyWindowInfo(options, CGWindowID(0))
let infoList = windowListInfo as NSArray? as? [[String: AnyObject]]

但是似乎没有 windows 标题的信息。

如何获取 CGWindowID 或任何信息以按标题指定 window？

实际上，您发布的代码片段似乎对我有用。我所做的只是遍历字典并找到给定 window 标题的 window 信息。

代码如下：

func getWindowInfo(pname: String) -> Dictionary<String, AnyObject> {
    var answer = Dictionary<String, AnyObject>()
    let options = CGWindowListOption(arrayLiteral: CGWindowListOption.optionOnScreenOnly)
    let windowListInfo = CGWindowListCopyWindowInfo(options, CGWindowID(0))
    let infoList = windowListInfo as NSArray? as? [[String: AnyObject]]


    infoList?.forEach{eachDict in
        eachDict.keys.forEach{ eachKey in
            if (eachKey == "kCGWindowName" && eachDict[eachKey] != nil ){
                let name = eachDict[eachKey] as? String ?? ""
                print (name)
                if ( name == pname){
                    print("******** Found **********")
                    answer = eachDict as! Dictionary<String, AnyObject>
                }
            }
            print(eachKey , "-->" , eachDict[eachKey])
        }
    }
    return answer
}

通过上面的函数，我可以得到一个window的详细信息，比如名字。

我希望它也对你有用。
