Programmatically create NSWindow
提问by user3345978
I want to programmatically create a new NSWindow, but I can't find a way to succeed. This simple code doesn't display a new window. What's wrong with it?
我想以编程方式创建一个新的 NSWindow，但我找不到成功的方法。这个简单的代码不会显示一个新窗口。它出什么问题了？
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {
@IBOutlet weak var window: NSWindow!
func applicationDidFinishLaunching(aNotification: NSNotification) {
let win = NSWindow(contentRect: NSMakeRect(100, 100, 600, 200),
styleMask: NSResizableWindowMask,
backing: NSBackingStoreType.Buffered, defer: true)
let controller = NSWindowController(window: win)
controller.showWindow(self)
win.makeKeyAndOrderFront(win)
}
}

newWindow.isOpaque = false
newWindow.center()
newWindow.isMovableByWindowBackground = true
newWindow.backgroundColor = NSColor(calibratedHue: 0, saturation: 1.0, brightness: 0, alpha: 0.7)
newWindow.makeKeyAndOrderFront(nil)
}
func applicationDidFinishLaunching(_ aNotification: Notification) {
createNewWindow()

func applicationWillTerminate(_ aNotification: Notification) {
// Insert code here to tear down your application
}

Here's a working example without any bells & whistles, updated to Swift 4.2.
这是一个没有任何花里胡哨的工作示例，已更新到 Swift 4.2。
It creates a bare window, with & without a nib depending on which function you call.
它创建一个裸窗口，根据您调用的函数，带有和不带有笔尖。
In IB, uncheck "initial controller" everywhere. For the nib version to work, you must give the IB-supplied window controller a storyboard ID of "WindowController."
在 IB 中，取消选中“初始控制器”。要使 nib 版本正常工作，您必须为 IB 提供的窗口控制器提供“WindowController”的故事板 ID。
import Cocoa
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate, DebugHelper {
var myName: String = "AppDelegate"
var windowController: NSWindowController!
var window: NSWindow!
func applicationDidFinishLaunching(_ aNotification: Notification) {
//nib()
diy()
}
func nib() {
let storyboard = NSStoryboard(name: NSStoryboard.Name("Main"), bundle: nil)
guard let wc = storyboard.instantiateController(withIdentifier: "WindowController") as? NSWindowController else { return }
windowController = wc
wc.showWindow(self)
}
func diy() {
window = NSWindow()
window.styleMask = NSWindow.StyleMask(rawValue: 0xf)
window.backingType = .buffered
window.contentViewController = ViewController()
window.setFrame(NSRect(x: 700, y: 200, width: 500, height: 500), display: false)
windowController = NSWindowController()
windowController.contentViewController = window.contentViewController
windowController.window = window
windowController.showWindow(self)
}
func applicationWillTerminate(_ aNotification: Notification) {
// Insert code here to tear down your application
}
}
import Cocoa
class ViewController: NSViewController, DebugHelper {
var myName: String = "ViewController"
override func loadView() {
view = NSView()
}
}
