macos – 根据变量swift调整窗口大小

我有一个NSViewController和一个变量num.我想根据该变量动态地改变窗口的大小.有没有办法在 swift中做到这一点？

假设您的窗口有一个名为“window”的IBOutlet,您的动态编号名为“myDynamicNumber”：

func resize() {
    var windowFrame = window.frame
    let oldWidth = windowFrame.size.width
    let oldHeight = windowFrame.size.height
    let toAdd = CGFloat(myDynamicNumber)
    let newWidth = oldWidth + toAdd
    let newHeight = oldHeight + toAdd
    windowFrame.size = NSMakeSize(newWidth,newHeight)
    window.setFrame(windowFrame,display: true)
}
