If you want to create a separate class for New Window, these are the steps:
如果你想为新窗口创建一个单独的类，这些是步骤：
- Create a class which is a sub class of NSWindowController e.g. NewWindowController
- Create a window xib for NewWindowController class.
On button click code as:
NewWindowController *windowController = [[NewWindowController alloc] initWithWindowNibName:@"You Window XIB Name"]; [windowController showWindow:self];
- 创建一个类，它是 NSWindowController 的子类，例如 NewWindowController
- 为 NewWindowController 类创建一个窗口 xib。
在按钮上单击代码为：
NewWindowController *windowController = [[NewWindowController alloc] initWithWindowNibName:@"You Window XIB Name"]; [windowController showWindow:self];

NSWindowController * wc=[[NSWindowController alloc] initWithWindowNibName:@"your_nib_name"];
[wc showWindow:self];

Swift 3: In your storyboard go to WindowController -> Identity inspector -> storyBoardID: fill out: mainWindow. Then from your current viewcontroller link the button on the storyboard to the following method:
Swift 3：在您的故事板中，转到 WindowController -> Identity inspector -> storyBoardID：填写：mainWindow。然后从您当前的视图控制器将故事板上的按钮链接到以下方法：
@IBAction func newWindow(_ sender: Any) {
let myWindowController = self.storyboard!.instantiateController(withIdentifier: "mainWindow") as! NSWindowController
myWindowController.showWindow(self)
}

Yes, but the window closes if this code is inside of some func. Here is solution.
是的，但是如果此代码在某个 func 内，则窗口将关闭。这是解决方案。
In blah.h
在 blah.h
@interface blah : NSObject {
...
NewWindowController *controllerWindow;
...
}
In blah.m
在 blah.m
@implementation
...
-(IBAction)openNewWindow:(id)sender {
controllerWindow = [[NewWindowController alloc] initWithWindowNibName:@"You Window XIB Name"];
[controllerWindow showWindow:self];
}
...
