使用Storyboard的NSWindowController自动保存

问题描述

我有一个Swift应用程序，它正在启动一个简单的NSWindow，如下所示:

I have a Swift application that is launching a simple NSWindow, like so:

func applicationDidFinishLaunching(notification: NSNotification!) {
    let storyboard = NSStoryboard(name: "MainStoryboard", bundle: NSBundle.mainBundle())
    windowController = storyboard.instantiateInitialController() as? NSWindowController
    windowController?.showWindow(self)
}

这很好用，我的应用程序启动并显示窗口. 但是:大小始终相同.

This works great, my app launches and the window appears. However: The size is always the same.

在情节提要中，我指定了Autosave名称:

In the storyboard, I have specified an Autosave name:

请注意，还选中了Restorable复选框.

Note also the Restorable checkbox is checked.

但是无论如何，窗口每次都会显示相同的大小.在过去，这始终是有效的"，因此我无法确定这是错误还是缺失的部分.手动实例化和显示窗口时，自动保存会自动与情节提要一起使用吗?

But regardless, the window appears the same size, every time. This has always "just worked" in the past, so I can't tell if this is a bug, or a piece I'm missing. Does autosaving automatically work with storyboards when instantiating and showing windows manually?

推荐答案

这似乎是Xcode错误.我可以通过手动设置NSWindowController windowFrameAutosaveName属性来解决该问题:

This seems to be an Xcode bug. I was able to workaround it by manually setting the NSWindowController windowFrameAutosaveName property:

windowController?.windowFrameAutosaveName = "Main App Window"

但是...仅当属性设置为与Interface Builder中显示的值不同的 值时，这才对我有用.如果以编程方式将其设置为与IB中使用的值相同，那么它将不起作用.

However... This only worked for me if the property was set to a different value than what is displayed in Interface Builder. If it's programmatically set to the same value that's being used in IB, it doesn't work.

因此在IB中，自动保存名称保留为MainAppWindow，并以编程方式将其设置为Main App Window.

So in IB the autosave name is left to MainAppWindow, and programmatically it's set to Main App Window.
