如何在OSX应用程序中还原窗口位置? [英] How to restore window position in an OSX application?

问题描述

我创建了一个情节提要，它具有窗口视图控制器作为初始视图控制器.我给窗口一个自动保存的名称preferencesWindow.在首选项中，我选择了[x]可恢复，关闭时[x]释放.

I created a storyboard it has window view controller as initial view controller. I gave the window an autosave name preferencesWindow. In the preferences I checked [x] Restorable and [x] Release when closed.

当我进入菜单并单击首选项"时，我将像这样加载窗口控制器:

When I go into the menu and click Preferences I load the window controller like so:

    let storyboard          = NSStoryboard(name: "Preferences", bundle: nil)
    let windowController    = storyboard.instantiateInitialController() as? NSWindowController
    let window              = windowController?.window

    windowController!.showWindow(self)

这将显示首选项视图控制器，当我将其拖动到另一个位置并单击关闭按钮时，它将关闭.到目前为止，一切都很好.但是，当我再次从菜单加载窗口时，它显示在其原始位置，而不是我上次将窗口拖动到的位置.为什么会这样?

This will present the preferences view controller and when I drag it to another position and click the close button it will close. So far so good. However when I load the window again from the menu, it shows on it's original position instead of the position I last dragged the window to. Why is this?

答案 在xCode 7中设置代码中的自动保存名称似乎可以解决该错误.

Answer It appears to be a bug in xCode 7 setting the auto save name in code solved it.

    let storyboard          = NSStoryboard(name: "Preferences", bundle: nil)
    let windowController    = storyboard.instantiateInitialController() as? NSWindowController
    let window              = windowController?.window

    window!.setFrameAutosaveName("preferences")
    windowController!.showWindow(self)

推荐答案

这是Xcode 6中的错误，我不知道Xcode 7中是否已解决.

This is a bug in Xcode 6 and I don't know if it is fixed in Xcode 7.

在InterfaceBuilder中设置自动保存无效.要使其正常工作，只需在windowController的windowDidLoad()中设置其名称:

Setting autosave in InterfaceBuilder has no effect. To get it to work just set its name in windowDidLoad() of your windowController:

class MyWindowController: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()

        self.windowFrameAutosaveName = "position"
    }    
}
