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)
}

在 Swift 3 中调整窗口大小,使用setFrame。
ViewController的一个例子:
func resizeWin(size:(CGFloat,CGFloat)){
self.view.window?.setFrame(NSRect(x:0,y:0,width:size.0,height:size.1), display: true)
}

我需要切换查看文本视图,因此我将窗口覆盖了一个不可见的视图 - hideRect只是文本视图的缩写;通过这种方式,我可以调整大小(hideRect)并稍后恢复到原始大小 - origRect。在viewDidLoad()处捕获隐藏和原始rect。 Swift 3 / Xcode 8.3.3
// class global contants
let kTitleUtility = 16
let kTitleNormal = 22
@IBOutlet var hideView: NSView!
var hideRect: NSRect?
var origRect: NSRect?
@IBAction func toggleContent(_ sender: Any) {
// Toggle content visibility
if let window = self.view.window {
let oldSize = window.contentView?.bounds.size
var frame = window.frame
if toggleButton.state == NSOffState {
frame.origin.y += ((oldSize?.height)! - (hideRect?.size.height)!)
window.setFrameOrigin(frame.origin)
window.setContentSize((hideRect?.size)!)
window.showsResizeIndicator = false
window.minSize = NSMakeSize((hideRect?.size.width)!,(hideRect?.size.height)!+CGFloat(kTitleNormal))
creditScroll.isHidden = true
}
else
{
let hugeSize = NSMakeSize(CGFloat(Float.greatestFiniteMagnitude), CGFloat(Float.greatestFiniteMagnitude))
frame.origin.y += ((oldSize?.height)! - (origRect?.size.height)!)
window.setFrameOrigin(frame.origin)
window.setContentSize((origRect?.size)!)
window.showsResizeIndicator = true
window.minSize = NSMakeSize((origRect?.size.width)!,(origRect?.size.height)!+CGFloat(kTitleNormal))
window.maxSize = hugeSize
creditScroll.isHidden = false
}
}
}
这也保留了寡妇的视觉起源和最小化。
