NSViewController-Close window-Swift-Storyboard

提问by Fredo

I cannot find the right way to close the main window after I clicked the "proceed" button installed on this window. I have try to connect this button to the "proceedclose" option of the inspector. I have also try to insert the following line inside my code :

单击此窗口上安装的“继续”按钮后，我找不到关闭主窗口的正确方法。我尝试将此按钮连接到检查器的“proceedclose”选项。我还尝试在我的代码中插入以下行：

import Cocoa
class ViewController: NSViewController {
    ...
    @IBAction func Envoi(sender: NSButton) {    
        self.view.window!.close()
    }
}

None of them works, nothing happens and no error is reported. Could anyone help me to sort it out?

它们都不起作用，没有任何反应，也没有报告错误。谁能帮我整理一下？

I had same question. And your code was very helpful for me.

我有同样的问题。你的代码对我很有帮助。

Then I checked "VC <- view <- window <- windowController" out in NS Lib. hierarchey has.

然后我在 NS Lib 中检查了“VC <- view <- window <- windowController”。层次结构有。

When you close window from VC, avoiding storyboard grow bizzare. you can solve this, by

当你从 VC 关闭窗口时，避免故事板变得奇怪。你可以解决这个问题，通过

self.view.window?.windowController?.close()

Just a quick note.

只是一个快速的笔记。

1. Be aware of each NSViewController & NSButton instance. Fix management of NSViewController & NSButton instances if needed.

1. 注意每个 NSViewController 和 NSButton 实例。如果需要，修复 NSViewController 和 NSButton 实例的管理。

class ViewController: NSViewController {
    @IBOutlet weak var envoiButton: NSButton!
    …
    @IBAction func doEnvoiButtonPressed(_ sender: NSButton) {    
        print(self.hash)
        print(self.envoiButton.hash)
        // … other code
    }
}

1. Set isReleasedWhenClosedin either the Interface Builder or in code, if needed.

2. Closed the window via the NSButton @IBAction(e.g. Envoi) with one of the following

   • self.view.window!.windowController!.close()NSWindowController close()abrupt close without possibility to ask user for confirmation.
   • self.view.window!.close()NSWindow close()sends willCloseNotificationnotification.
   • self.view.window!.performClose(nil)or self.view.window!.performClose(self)NSWindow performClose(_:)sends to all window closing signals. First, windowShouldClose(_:)to window delegate if present. If no delegate is present, then invokes any NSWindow object windowShouldClose(_:)implementation. If windowShouldClose(_:)returns true or is not implemented, then NSWindow close()is called. (performClose(_:)is the more comprehensive and flexible choice)

2. 设置isReleasedWhenClosed无论是在界面生成器或代码，如果需要的话。

3. @IBAction使用以下任一方法通过 NSButton （例如 Envoi）关闭窗口

   • self.view.window!.windowController!.close()NSWindowController close()突然关闭而无法要求用户确认。
   • self.view.window!.close()NSWindow close()发送willCloseNotification通知。
   • self.view.window!.performClose(nil)或NSWindow performClose(_:)发送到所有窗口关闭信号。首先，如果存在窗口委托。如果不存在委托，则调用任何 NSWindow 对象实现。如果返回 true 或未实现，则调用。（是更全面、更灵活的选择）self.view.window!.performClose(self)windowShouldClose(_:)windowShouldClose(_:)windowShouldClose(_:)NSWindow close()performClose(_:)

class ViewController: NSViewController {
    @IBAction func doEnvoiButtonPressed(_ sender: NSButton) {    
        self.view.window!.performClose(nil) // or performClose(self)
    }
}

It is working by using "self.view.window!.close()" inside the button action, but when I add a new ViewController, and link the button to it, the first window does not disappear anymore.

它通过在按钮操作中使用“self.view.window!.close()”来工作，但是当我添加一个新的 ViewController 并将按钮链接到它时，第一个窗口不再消失。

I'm assuming you may have forgotten to duplicate the @IBAction func Envoi(sender: NSButton)in the new ViewController? By doing this only your new window will close and not the first window.

我假设您可能忘记@IBAction func Envoi(sender: NSButton)在新的 ViewController 中复制？这样做只会关闭您的新窗口，而不是第一个窗口。
