Question

我正在使用以下代码添加启动画面，但看到崩溃会在2秒后关闭

@IBOutlet var customView: NSView!

override func viewDidLoad() {
    super.viewDidLoad()

    let splashScreen : NSImageView

   let rect : NSRect = NSMakeRect(0, 0, 421, 231)
   let splashWindow : NSWindow = NSWindow.init(contentRect: rect, styleMask: .borderless, backing: .buffered, defer: true)
    splashScreen = NSImageView.init(frame: rect)
    splashScreen.imageScaling = .NSScaleToFit
    splashScreen.image = NSImage.init(named: "splashScreen.jpg")
    customView.addSubview(splashScreen)

    let xPos :CGFloat = splashWindow.screen!.frame.width / 2 - splashWindow.frame.width / 2
    let yPos : CGFloat = splashWindow.screen!.frame.width / 2 - splashWindow.frame.width / 2
     splashWindow.setFrame(NSRect(x: xPos, y: yPos, width: splashWindow.frame.width, height: splashWindow.frame.height), display: true)
    sleep(2)

splashWindow.close（）

崩溃发生在

splashWindow.close()

我也尝试替换

splashWindow.perform(#selector(splashWindow.close), with: nil, afterDelay: 2)

但是不走运，如果您能指出一些教程，以使用swift将启动屏幕添加到可可应用中，这将对您大有帮助
