Cocoa应用程序菜单栏无法点击

Question

我正在我的cocoa应用程序中使用以下代码在@implementation我的自定义应用程序中构建一个菜单栏CustomApplication:

+(void) setUpMenuBar
{
  [CustomApplication sharedApplication];

  // Main menu
  NSMenu* mainMenu = [NSApp mainMenu];
  if (mainMenu != nil) return; // We set it already
  mainMenu = [[[NSMenu alloc] initWithTitle:@""] autorelease];
  [NSApp setMainMenu:mainMenu];

  // Application menu
  NSMenuItem* appleItem = [mainMenu addItemWithTitle:@""
                                              action:nil
                                       keyEquivalent:@""];

  NSString* appName = @"MyApp";

  NSMenu* appleMenu = [[NSMenu alloc] initWithTitle:@""];

  // Apple menu
  [appleMenu addItemWithTitle:[@"About " stringByAppendingString:appName]
                       action:@selector(orderFrontStandardAboutPanel:)
                keyEquivalent:@""];

  // Quit
  [appleMenu addItemWithTitle:[@"Quit " stringByAppendingString:appName]
                                        action:@selector(terminate:)
                                        keyEquivalent:@"q"];

  [appleItem setSubmenu:[appleMenu autorelease]];
}

在启动时,我的应用程序获得焦点,但菜单栏不可克服.但是,如果我再次单击窗口并将其重新放回(将焦点返回给应用程序),它将变为可单击并正常工作.

我错过了什么？

UPDATE

当我按如下方式创建应用程序时调用此方法. [更新]这是我正在开始我的应用程序.它实际上是从任何@implementation一个类之外的ocaml绑定中调用的第一件事.

CustomApplicationDelegate* delegate = [CustomApplicationDelegate new];

[CustomApplication sharedApplication];
[NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];
[NSApp activateIgnoringOtherApps:YES];

[[NSApplication sharedApplication] setDelegate:delegate];

[CustomApplication setUpMenuBar];

[[CustomApplication sharedApplication] finishLaunching];

Answer 1

好的,感谢@bhaller的评论,我能够解决我的问题.

我实际上将调用转移给了代理,如下所示.

-(void)applicationWillFinishLaunching:(NSNotification *)aNotification
{
  [CustomApplication sharedApplication];
  [CustomApplication setUpMenuBar];
  [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];
}

-(void)applicationDidFinishLaunching:(NSNotification *)notification
{
  [CustomApplication sharedApplication];

  [NSApp activateIgnoringOtherApps:YES];
}
