以编程方式设置NSWindow Size不起作用

我是macOS的新手,并且有一个非常简单的项目,在ViewController中只有一个标签。在WindowController中,我尝试使用该代码设置窗口的大小:

    import Cocoa

class WindowController: NSWindowController {

  override func windowDidLoad() {
    super.windowDidLoad()
    if let window = window, let screen = NSScreen.main {
      let screenRect = screen.visibleFrame
      print("screenRect \(screenRect)")

    window.setFrame(NSRect(x: screenRect.origin.x, y: screenRect.origin.y, width: screenRect.width/2.0, height: screenRect.height/2.0), display: true, animate: true)
      print("windowFrame \(window.frame)")
      }
  }
}

日志显示:

screenRect (0.0, 30.0, 1680.0, 997.0)
windowFrame (0.0, 30.0, 840.0, 499.0)

但是,该窗口不会受到影响,即我输入的宽度/高度都保持不变。如果我用鼠标更改大小,下次打开时,将完全使用旧大小。

有什么主意,我可能会在分镜脚本或其他任何地方错过什么?在我看来,我忘记了一些东西,因为它是如此基本..... (标签限制在顶部,左侧,右侧)

...确实加载了...

   // decide if needed..
    let when = DispatchTime.now() + 0.5
    DispatchQueue.main.asyncAfter(deadline: when, execute: {  [weak self] in

        self?.setSize()

    })
}   //setupUI


private final func setSize(){
    if let w = self.view.window{
        var frame = w.frame
        frame.size = NSSize(width: 800, height: 600)
        w.setFrame(frame, display: true, animate: true)

    }
}

注意:在didLoad上没有一点延迟,它不起作用。 (无裁判...)

找到了它,这要感谢PUTTIN Why NSWindow animator setFrame:display:animate: didn't work sometimes?

神奇的是,将其放置在mainThread上

DispatchQueue.main.async {
window.setFrame(NSRect(x: screenRect.origin.x, y: screenRect.origin.y, width: screenRect.width/1.0, height: screenRect.height/1.0), display: true, animate: true)
  print("windowFrame \(window.frame)")
    }
}

现在可以了!
