如何使用 Swift 和 MacOS 隐藏顶部栏（带按钮）？

Question

我正在尝试从 window 中删除标题和顶部按钮，基本上只显示内容。我已经尝试过各种方法但没有成功，但没有任何明显的原因表明它不起作用。有关我尝试过的选项，请参阅 setVisibility 函数

AppDelagate.swift

 import Cocoa

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

    @IBOutlet weak var window: NSWindow!

    func setVisibility(){
        self.window?.titlebarAppearsTransparent = true;
        self.window?.styleMask = .borderless
        self.window?.titleVisibility = .hidden
        self.window?.styleMask.insert(.fullSizeContentView)
        /*
         self.window?.standardWindowButton(.zoomButton)!.isHidden = true
         self.window?.standardWindowButton(.closeButton)!.isHidden = true
         */
        self.window?.level = .floating
        self.window?.center()
        self.window?.collectionBehavior = .canJoinAllSpaces
        //self.window?.collectionBehavior = .moveToActiveSpace
    }

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        setVisibility()
        NSApp.activate(ignoringOtherApps: true)

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

    func applicationDidBecomeActive(_ aNotification: Notification) {
       setVisibility()
        NSApp.activate(ignoringOtherApps: true)

    }


    func applicationWillResignActive(_ aNotification: Notification) {
        setVisibility()
        NSApp.activate(ignoringOtherApps: true)

    }


    func applicationWillEnterForeground(_ aNotification: Notification) {
        setVisibility()
        NSApp.activate(ignoringOtherApps: true)

    }

    func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
        NSApp.terminate(self)
        return true
    }
}

ViewController.swift 我只是嵌入了一个 webkit 视图。没什么好看的。

import Cocoa
import WebKit
import os

class ViewController: NSViewController, WKUIDelegate, WKNavigationDelegate {
    @IBOutlet weak var window: NSWindow!



    let webView = WKWebView()
    override func viewDidLoad() {
        super.viewDidLoad()
        self.webView.uiDelegate = self
        self.webView.navigationDelegate = self
        webView.frame = CGRect(x: 0, y: 0, width: 1200, height: 600)
         view.addSubview(webView)
        let url = URL(string: "http://localhost:8080/?x=y")
        //let url = URL(string: "https://apple.com")
        let request = URLRequest(url: url!)
        webView.load(request)

    }


    public func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Swift.Void)
    {
            if navigationAction.request.url?.path == "/close" || navigationAction.request.url?.path == "/close/"{
                exit(0);
            }
        decisionHandler(.allow)
    }

    override var representedObject: Any? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

您想要的是带有 NSWindowStyleMaskBorderless 类型样式掩码的 window。问题是这必须在初始化 window 时设置。这就是为什么你的行 self.window?.styleMask = .borderless 没有效果。

因为您正在使用 Interface Builder 创建 window，所以您必须打开相应的 xib 文件（我猜 MainMenu.xib），select window 和 deselect Title Bar 在属性检查器中：

我知道。这令人困惑。但至少 Apple 在 documentation:

中提到了它

Note that you can set a window’s or panel’s style mask to NSWindowStyleMaskBorderless in Interface Builder by deselecting Title Bar in the Appearance section of the Attributes inspector.

如果您想详细了解 NSWindow 结帐 NSWindowStyles by Luka Kerr 的不同风格。这是一个很好的参考。

更新： 在上述参考资料中，我找到了另一种删除可能适合您的标题栏的方法：

window?.styleMask.remove(.titled)
