在Objective-C中以编程方式创建Mojave Cocoa窗口

#import <Cocoa/Cocoa.h>

@interface MyWindowController : NSWindowController

@end

@implementation MyWindowController

- (void)windowDidLoad {
    [super windowDidLoad];
    
    // 在窗口加载完成后进行一些初始化操作
}

@end

@interface AppDelegate : NSObject <NSApplicationDelegate>

@end

@implementation AppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    // 应用程序完成启动时执行的代码
    
    // 创建窗口控制器并显示窗口
    MyWindowController *windowController = [[MyWindowController alloc] initWithWindowNibName:@"MyWindowController"];
    [windowController showWindow:self];
}

@end

int main(int argc, const char * argv[]) {
    NSApplication *application = [NSApplication sharedApplication];
    AppDelegate *delegate = [[AppDelegate alloc] init];
    [application setDelegate:delegate];
    [application run];
    
    return EXIT_SUCCESS;
}
