我的代码如下：

// KRApplicationDelegate.m

- (void)applicationDidFinishLaunching:(NSNotification *)notification {
    NSLog(@"%s",__PRETTY_FUNCTION__);
    KRAuthenticationWindowController *authWindowController = [[KRAuthenticationWindowController alloc] init];
    [authWindowController showWindow:nil];
    [[authWindowController window] makeKeyAndOrderFront:nil];
}

// KRAuthenticationWindowController.m

- (id)init {
    self = [super initWithWindowNibName:@"AuthenticationWindow"];
    if(!self) return nil;
    NSLog(@"%s",__PRETTY_FUNCTION__);
    return self;
}

- (void)loadWindow {
    [super loadWindow];
    [self.window setBackgroundColor:[NSColor colorWithDeviceWhite:0.73 alpha:1]];
    NSLog(@"%s",__PRETTY_FUNCTION__);
}

- (void)windowDidLoad {
    [super windowDidLoad];
    NSLog(@"%s",__PRETTY_FUNCTION__);
}

- (void)showWindow:(id)sender {
    [super showWindow:sender];
    NSLog(@"%@",self.window);
    NSLog(@"%s",__PRETTY_FUNCTION__);
}

我的控制台输出：

2013-02-24 16:21:45.420 Application[3105:303] -[KRApplicationDelegate applicationDidFinishLaunching:]
2013-02-24 16:21:45.421 Application[3105:303] -[KRAuthenticationWindowController init]

2013-02-24 16:21:45.556 Application[3105:303] -[KRAuthenticationWindowController showWindow:]

我想我只是想念一些重要的东西.任何帮助将不胜感激.
