就像标题一样，[myWindowController showWindow:nil]不起作用。以下是您可能需要了解的一些事实：

  • 我的窗口控制器：KRAuthenticationWindowController
  • 界面生成器文件：AuthenticationWindow.xib
  • 文件的所有者是KRAuthenticationWindowController
  • window插座连接到窗户
  • Window'sdelegate已连接到 File's Owner
  • 窗口Visible at launch未选中
  • Window的Release when closed也未选中

我的代码如下所示：

// 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 16:21:45.428 Application[3105:303] -[KRAuthenticationWindowController loadWindow]
2013-02-24 16:21:45.428 Application[3105:303] -[KRAuthenticationWindowController windowDidLoad]
2013-02-24 16:21:45.556 Application[3105:303] <NSWindow: 0x10016e860>
2013-02-24 16:21:45.556 Application[3105:303] -[KRAuthenticationWindowController showWindow:]

我想我只是错过了一些重要的东西。任何帮助，将不胜感激。

尝试将 authWindowController 转换为实例变量。目前，它是一个局部变量。当局部变量消失时，窗口控制器和带有它的窗口可能会被释放，因此它永远不会被显示。
