如何在单击左上角的红点时以编程方式终止MacOS应用程序？

@interface AppDelegate : NSObject <NSApplicationDelegate, NSWindowDelegate>
@end

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    // 设置窗口的代理为AppDelegate
    NSWindow *window = NSApp.mainWindow;
    window.delegate = self;
}

- (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)sender {
    // 返回YES表示关闭最后一个窗口后终止应用程序
    return YES;
}

- (BOOL)windowShouldClose:(id)sender {
    // 在窗口关闭时终止应用程序
    [NSApp terminate:self];
    return YES;
}

@end

class AppDelegate: NSObject, NSApplicationDelegate, NSWindowDelegate {
    func applicationDidFinishLaunching(_ aNotification: Notification) {
        // 设置窗口的代理为AppDelegate
        NSApp.mainWindow?.delegate = self
    }
    
    func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
        // 返回true表示关闭最后一个窗口后终止应用程序
        return true
    }
    
    func windowShouldClose(_ sender: Any) -> Bool {
        // 在窗口关闭时终止应用程序
        NSApp.terminate(self)
        return true
    }
}

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSApplication *application = [NSApplication sharedApplication];
        AppDelegate *delegate = [[AppDelegate alloc] init];
        application.delegate = delegate;
        [application run];
    }
    return 0;
}

import Cocoa

let delegate = AppDelegate()
NSApplication.shared.delegate = delegate
_ = NSApplicationMain(CommandLine.argc, CommandLine.unsafeArgv)
