一个可直接替换 NSComboButton 的控件，并支持 macOS 13 之前的版本。

当您想采用 NSComboButton 但又必须保持与 10.13 的兼容性时使用。

DSFComboButton 尝试尽可能地匹配 NSComboButton 控件的 API。编程接口几乎相同，但是（不幸的是）自定义控件中的 Interface Builder 支持非常有限，所以我已尽力而为。

样式	描述
`.split`	一种样式，将按钮的标题和图像与人们用于激活按钮的菜单指示器分开。
`.unified`	一种样式，将按钮的标题和图像与菜单指示器统一起来。

属性	类型	描述
`样式`	`DSFComboButton.Style`	要使用的控件样式
`title`	`String`	要在控件上显示的文本
`image`	`NSImage`	要在控件上显示的图像
`imageScaling`	`NSImageScaling`	图像如何缩放
`target`	`AnyObject`	按钮操作的目标
`action`	`Selector`	要在目标上调用的选择器
`controlSize`	`NSControl.ControlSize`	控件的大小

let button = DSFComboButton()
button.menu = NSMenu(...)

let button = DSFComboButton()
button.target = /*some controller*/
button.action = #selector(buttonPressed(_:))
