Apple has some useful sample code on Nib Loading. It doesn't directly address this question however; the following code does.
Apple 在Nib Loading上有一些有用的示例代码。然而，它并没有直接解决这个问题；下面的代码可以。
@interface CloseWindowAppDelegate : NSObject <NSApplicationDelegate> {
NSWindow *window;
IBOutlet NSWindow * secondWindow;
NSNib * secondNib;
}
@property (assign) IBOutlet NSWindow *window;
- (IBAction)openSecondWindow:(id)sender;
- (IBAction)closeSecondWindow:(id)sender;
@end
#import "CloseWindowAppDelegate.h"
@implementation CloseWindowAppDelegate
@synthesize window;
- (IBAction)openSecondWindow:(id)sender {
secondNib = [[NSNib alloc] initWithNibNamed:@"SecondWindow" bundle:nil];
[secondNib instantiateNibWithOwner:self topLevelObjects:nil];
[secondWindow makeKeyAndOrderFront:nil];
}
- (IBAction)closeSecondWindow:(id)sender {
[secondWindow close];
[secondNib release];
}
@end

This is for someone who is using Swiftand NSStoryBoardSegue, here is the same way to achieve it
这适用于正在使用Swiftand 的人NSStoryBoardSegue，这是实现它的相同方法
NSApplication.sharedApplication().mainWindow?.close() // close current window first
self.performSegueWithIdentifier("id_of_your_segue", sender: self) // open the second view by invoking the segue that is set to connect two views.

U may use "performClose" action. Choose nib file (your window which u wont closed), open Connections inspector, connect "performClose" action with u button.
你可以使用“performClose”动作。选择 nib 文件（您不会关闭的窗口），打开连接检查器，使用 u 按钮连接“performClose”操作。
