Mac OS X - 监控应用程序启动?

发布于 2024-09-18 10:00:41 字数 188 浏览 7 评论 0原文

我想为 Mac OS X 编写一个简单的菜单栏应用程序。用户只想在打开 Safari 时使用该应用程序。为了避免不必要地混乱菜单栏,我想根据 Safari 是否打开来隐藏和显示菜单栏图标。

我的应用程序是否可以注册一些通知?我能想象的唯一解决方法是轮询正在运行的进程并查看 Safari 是否已启动,但这似乎不是解决我的问题的优雅方法......

I want to write a simple menubar app for Mac OS X. The user will only want to use that app when Safari is opened. To not clutter the menubar unnecessarily, I want to hide and show the menubar icon depending on whether Safari is open or not.

Is there maybe some notification that my app could register for? The only workaround I can imagine is poll the running processes and see if Safari is launched, but that doesn't seem to be an elegant way to solve my problem...

NSWorkspaceDidLaunchApplicationNotificationNSWorkspaceDidTerminateApplicationNotification。 (有等效的碳事件。)

NSWorkspaceDidLaunchApplicationNotification and NSWorkspaceDidTerminateApplicationNotification. (There are equivalent Carbon Events.)

在 Carbon 事件管理器中使用 kEventAppFrontSwitched 来获取通知另一个应用程序变为活动状态。

Use kEventAppFrontSwitched in Carbon Event Manager to get notifications when another application becomes active.

使用此代码: http://cl.ly/2LbB

// usleep(40500);

ProcessNotif * x = [[ProcessNotif new] autorelease];
[x setProcessName: @"Safari"];
[x setTarget: self];
[x setAction: @selector(doStuff)];
[x start];

这将运行选择器 -doStuff< /code> 当 Safari 运行时。如果出现错误,请取消注释 usleep() 行。

Use this code: http://cl.ly/2LbB

// usleep(40500);

ProcessNotif * x = [[ProcessNotif new] autorelease];
[x setProcessName: @"Safari"];
[x setTarget: self];
[x setAction: @selector(doStuff)];
[x start];

This will run the selector -doStuff when Safari runs. If you get an error, uncomment the usleep() line.

遇到了同样的问题,但感谢 JWWalker、文档和谷歌编写了以下代码:

// i need to register on button event, you can do it even in applicationDidFinishLaunching
- (IBAction)Btn_LoginAction:(id)sender {
    ...
    NSNotificationCenter *center = [[NSWorkspace sharedWorkspace] notificationCenter];
    [center addObserver:self selector:@selector(appLaunched:) name:NSWorkspaceDidLaunchApplicationNotification object:nil];
    [center addObserver:self selector:@selector(appTerminated:) name:NSWorkspaceDidTerminateApplicationNotification object:nil];
}

// remember to unregister
- (void)ManageLogout:(NSInteger)aResult {
    ...
    NSNotificationCenter *center = [[NSWorkspace sharedWorkspace] notificationCenter];
    [center removeObserver:self name:NSWorkspaceDidLaunchApplicationNotification object:nil];
    [center removeObserver:self name:NSWorkspaceDidTerminateApplicationNotification object:nil];
}

- (void)appLaunched:(NSNotification *)note {
    [GTMLogger myLog:kGTMLoggerLevelDebug fmt:@"MainWinDelegate::appLaunched: %@ (%@)\n", [[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"], [[note userInfo] objectForKey:@"NSApplicationProcessIdentifier"]];

    if ( [[[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"] isEqualToString:@"app.you.monitor.bundle.identifier"] ) {
        // do stuff
    }
}

- (void)appTerminated:(NSNotification *)note {
    [GTMLogger myLog:kGTMLoggerLevelDebug fmt:@"MainWinDelegate::appTerminated: %@ (%@)\n", [[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"], [[note userInfo] objectForKey:@"NSApplicationProcessIdentifier"]];

    if ( [[[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"] isEqualToString:@"app.you.monitor.bundle.identifier"] ) {
        // do stuff
    }
}

Got same problem, but thanks to JWWalker, documentation and google wrote this code:

// i need to register on button event, you can do it even in applicationDidFinishLaunching
- (IBAction)Btn_LoginAction:(id)sender {
    ...
    NSNotificationCenter *center = [[NSWorkspace sharedWorkspace] notificationCenter];
    [center addObserver:self selector:@selector(appLaunched:) name:NSWorkspaceDidLaunchApplicationNotification object:nil];
    [center addObserver:self selector:@selector(appTerminated:) name:NSWorkspaceDidTerminateApplicationNotification object:nil];
}

// remember to unregister
- (void)ManageLogout:(NSInteger)aResult {
    ...
    NSNotificationCenter *center = [[NSWorkspace sharedWorkspace] notificationCenter];
    [center removeObserver:self name:NSWorkspaceDidLaunchApplicationNotification object:nil];
    [center removeObserver:self name:NSWorkspaceDidTerminateApplicationNotification object:nil];
}

- (void)appLaunched:(NSNotification *)note {
    [GTMLogger myLog:kGTMLoggerLevelDebug fmt:@"MainWinDelegate::appLaunched: %@ (%@)\n", [[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"], [[note userInfo] objectForKey:@"NSApplicationProcessIdentifier"]];

    if ( [[[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"] isEqualToString:@"app.you.monitor.bundle.identifier"] ) {
        // do stuff
    }
}

- (void)appTerminated:(NSNotification *)note {
    [GTMLogger myLog:kGTMLoggerLevelDebug fmt:@"MainWinDelegate::appTerminated: %@ (%@)\n", [[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"], [[note userInfo] objectForKey:@"NSApplicationProcessIdentifier"]];

    if ( [[[note userInfo] objectForKey:@"NSApplicationBundleIdentifier"] isEqualToString:@"app.you.monitor.bundle.identifier"] ) {
        // do stuff
    }
}
