Cocoa 隐藏停靠图标而不隐藏菜单栏

我使用中的想法来选择性地隐藏我的应用程序的停靠图标。如果最终显示dock图标，则菜单栏也应显示。只是因为我没能做到这一点。菜单栏仍处于隐藏状态

因此，基本上，InfoPList中将“Application is agent”设置为“1”，并使用以下代码：

if (![[NSUserDefaults standardUserDefaults] boolForKey:@"LaunchAsAgentApp"]) {   
    ProcessSerialNumber psn = { 0, kCurrentProcess };
    TransformProcessType(&psn, kProcessTransformToForegroundApplication);
    SetSystemUIMode(kUIModeNormal, 0);
    [[NSWorkspace sharedWorkspace] launchAppWithBundleIdentifier:@"com.apple.dock"    options:NSWorkspaceLaunchDefault additionalEventParamDescriptor:nil launchIdentifier:nil];
    [[NSApplication sharedApplication] activateIgnoringOtherApps:TRUE];
}

那么，为什么菜单栏不显示，直到我隐藏并重新聚焦应用程序？这有什么解决办法吗？我看到启动时也没有显示菜单栏

编辑：我联系了苹果公司，他们给了我碳和非碳的解决方案。如果在Plist文件中将“应用程序是代理”设置为“是”，则此代码可用于

AppDelegate

类：

#define USE_CARBON  0

//
//  Note: NSLogDebug is defined in the projects pre-compiled (.pch) file
//

@implementation AppDelegate
{
    BOOL show_icon;
}

// Application will finish launching
- (void)applicationWillFinishLaunching:(NSNotification *)notification {
    NSLogDebug();
    NSURL *receiptUrl = [[NSBundle mainBundle] appStoreReceiptURL];
    if (![[NSFileManager defaultManager] fileExistsAtPath:[receiptUrl path]]) {
        // exit(173);
    }

#if 1
    show_icon = YES;
#else
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    NSString *hasDockIconDefaultsKey = @"Has Dock Icon?";
    // note: toggles value on each run (normally set from user pref pannel)
    show_icon = [userDefaults boolForKey:hasDockIconDefaultsKey];
    [userDefaults setBool:!show_icon forKey:hasDockIconDefaultsKey];
#endif // if 1
    if (show_icon) {
        [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];
        [NSApp setPresentationOptions:NSApplicationPresentationDefault];
        [NSMenu setMenuBarVisible:NO];
        [NSMenu setMenuBarVisible:YES];
    }

    [NSApp activateIgnoringOtherApps:YES];
}   // applicationWillFinishLaunching

// Application did finish launching
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    NSLogDebug();
    // Insert code here to initialize your application
    if (show_icon) {
#if USE_CARBON
        ProcessSerialNumber psn = {0, kCurrentProcess};
        OSStatus returnCode = TransformProcessType(&psn, kProcessTransformToForegroundApplication);
        if (noErr != returnCode) {
            NSLog(@"TransformProcessType error: %d (0x%0X)", returnCode, returnCode);
        }

        ProcessSerialNumber psnx = {0, kNoProcess};
        GetNextProcess(&psnx);
        SetFrontProcess(&psnx);
#else   // if 0
        NSWorkspace *sharedWorkspace = [NSWorkspace sharedWorkspace];
        NSRunningApplication * menuBarOwningApplication = [sharedWorkspace menuBarOwningApplication];
        (void) [menuBarOwningApplication activateWithOptions:NSApplicationActivateIgnoringOtherApps];
#endif
        [self performSelector:@selector(setFront) withObject:nil afterDelay:0.];
    }
}   // applicationDidFinishLaunching

// Close app when main window is closed
- (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)sender {
    return (YES);
}

- (void)setFront;
{
#if USE_CARBON
    ProcessSerialNumber psn = {0, kCurrentProcess};
    SetFrontProcess(&psn);
#else // if USE_CARBON
    [[NSRunningApplication currentApplication] activateWithOptions:NSApplicationActivateIgnoringOtherApps];
#endif  // USE_CARBON
}

@end

注意，我也提交了一份bug报告

以下是非碳解决方案的快速版本：

func applicationWillFinishLaunching(_ notification: Notification) {
    if  showIcon {
        NSApp.setActivationPolicy(.regular)
        NSApp.presentationOptions = []
        NSMenu.setMenuBarVisible(false)
        NSMenu.setMenuBarVisible(true)
    }
    NSApp.activate(ignoringOtherApps: true)
}

func applicationDidFinishLaunching(_ aNotification: Notification) {
    NSApplication.shared.activate(ignoringOtherApps: true)
    if  showIcon {
        let workspace = NSWorkspace.shared
        let application = workspace.menuBarOwningApplication
        application?.activate(options: .activateIgnoringOtherApps)
        self.perform(#selector(activate), with: nil, afterDelay: 0.0)
    }
}

@objc private func activate() {  
    NSRunningApplication.current.activate(options: .activateIgnoringOtherApps)
}

首先，在现代代码中，应该使用

-[NSApplication setActivationPolicy:

而不是

TransformProcessType（）

和

-[NSApplication setPresentationOptions:

而不是

setsystemimode（）

。如果切换到这些选项不足以解决菜单栏不更新的问题，我建议您尝试使用

-setPresentationOptions:

或

+[NSMenu setmenubavisible:

隐藏菜单栏，然后立即反转该操作

此外，停止尝试激活码头的业务

比如说：

if (![[NSUserDefaults standardUserDefaults] boolForKey:@"LaunchAsAgentApp"]) {
    [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular];
    [NSApp setPresentationOptions:NSApplicationPresentationDefault]; // probably not necessary since it's the default
    [NSMenu setMenuBarVisible:NO]; // these two lines may not be necessary, either; using -setActivationPolicy: instead of TransformProcessType() may be enough
    [NSMenu setMenuBarVisible:YES];
}

当我使用2

+[NSMenu setmenubavisible:

行时，这就行了-非常感谢Ken！哦，我仍然有一个问题-菜单栏现在显示，但它只在应用程序被隐藏和重新聚焦时响应点击。右侧的按钮（状态栏按钮，如聚光灯按钮）始终有响应。你知道这里可能会发生什么吗？不是马上，不是。听起来像是可可虫。当然，隐藏和显示菜单栏的必要性也是如此。好的，我会从苹果公司获得一些技术支持，并向您汇报，谢谢@BrunoVandekerkhove您是否解决了非责任菜单项的问题？我储备了同一批货
