在MacOS中绘制交互式二维绘图的最佳方法

import Cocoa

class CustomView: NSView {
    override func draw(_ dirtyRect: NSRect) {
        super.draw(dirtyRect)
        
        // 创建绘图上下文
        guard let context = NSGraphicsContext.current?.cgContext else { return }
        
        // 设置绘图参数
        context.setLineWidth(2.0)
        context.setStrokeColor(NSColor.red.cgColor)
        
        // 创建路径并绘制
        let path = NSBezierPath(rect: dirtyRect)
        path.stroke()
    }
    
    override func mouseDown(with event: NSEvent) {
        // 处理鼠标点击事件
        let location = convert(event.locationInWindow, from: nil)
        print("Mouse down at \(location)")
    }
}

// 创建窗口和视图
let frame = NSRect(x: 0, y: 0, width: 400, height: 400)
let window = NSWindow(contentRect: frame, styleMask: [.titled, .closable], backing: .buffered, defer: false)
let view = CustomView(frame: frame)

// 将视图添加到窗口中
window.contentView = view

// 显示窗口
window.makeKeyAndOrderFront(nil)

// 进入主循环
NSApplication.shared.run()
