为 NSStatusItem 图像缩放 PDF 图像

Question

我正在尝试创建一个 macOS 应用程序，其状态栏项目使用 PDF 而不是 PNG 图像，但是当我使用该图像时，它被过度缩放并且整个状态项目是黑色的。我找不到一种方法来缩放图像以使其适合 mac 状态栏项目的其余部分。

  • （我无法附上pdf所以你需要手动转换它）

Assets.xcassets

AppDelegate.swift

import Cocoa

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

    let statusItem = NSStatusBar.system.statusItem(withLength:NSStatusItem.squareLength)

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        // Insert code here to initialize your application
        if let button = statusItem.button {
          button.image = NSImage(named:NSImage.Name("status-logo"))
          button.action = #selector(printQuote(_:))
        }
    }

    @objc func printQuote(_ sender: Any?) {
      let quoteText = "Never put off until tomorrow what you can do the day after tomorrow."
      let quoteAuthor = "Mark Twain"

      print("\(quoteText) — \(quoteAuthor)")
    }

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

Answer 1

您应该调整 pdf 的大小，使其适合 statusItem 的按钮，如下所示：

    guard let logo = NSImage(named: NSImage.Name("status-logo")) else { return }

    let resizedLogo = NSImage(size: NSSize(width: 18, height: 18), flipped: false) { (dstRect) -> Bool in
        logo.draw(in: dstRect)
        return true
    }

然后设置button.image = resizedLogo
