MacOS - 细节问题小结

开发中遇到的一些细节问题总结如下：

鼠标事件

• 功能键（如判断是否按下了command、shift、control、option键等）

override func mouseDown(with event: NSEvent) {
        //获取鼠标点击位置坐标
        let inWindowlocation = event.locationInWindow
        //转化成视图的本地坐标
        let inViewPoint = self.view.convert(inWindowlocation, to: nil)
        print("inWindowlocation = \(inWindowlocation), \n inViewPoint = \(inViewPoint)")
        
        //MARK: - 功能键处理
        if event.modifierFlags.contains(.command) {
            //是否按下了命令建
            print("input command ...")
        } else {
            print("no input command ...")
        }
        
        super.mouseDown(with: event)
}
