Question

尝试使用以下内容设置swift即时Use of unresolved identifier 'window'错误时设置窗口级别：

window.level = Int(CGWindowLevelForKey(Int32(kCGScreenSaverWindowLevelKey)))

或

window.level = NSScreenSaverWindowLevel

Ive经过检查 这里How to set window level in Swift

此处Mac OS X, make a window go over menu bar

此处NSWindow Class

我似乎无法访问NSViewController或NSWindowController窗口属性

Answer 1

Swift 2更新：

panel.level = Int(CGWindowLevelForKey(CGWindowLevelKey.PopUpMenuWindowLevelKey))

Answer 2

子类NSWindowController

windowDidLoad()

中的

window?.level = Int(CGWindowLevelForKey(Int32(kCGScreenSaverWindowLevelKey)))

Answer 3

Swift 3更新：

window.level = Int(CGWindowLevelForKey(CGWindowLevelKey.popUpMenuWindow))
