How can I terminate my app in a helper app with sandboxing enabled?

问题

I've created a helper app, which monitors iTunes and launches/terminates the main app.

The launching works perfectly. The only problem is that I'm not allowed to terminate the main app, because of sandboxing. I get those 3 logs:

12/23/12 8:45:37.522 PM appleeventsd[70]: Sandboxed application with pid 8293 attempted to lookup App:"Significator 2"/8877/0x0:0x150150 ???? sess=100011 but was denied due to sandboxing. (handleMessage()/appleEventsD.cp #2007) com.apple.coreservices.appleevents.peer.0x7fd9c2401f00.xpcq

12/23/12 8:45:37.873 PM sandboxd[8888]: ([8293]) SignificatorHelp(8293) deny appleevent-send ch.ilijatovilo.significator-2

I've tried terminating it like this in the helper app:

NSRunningApplication *app = [[NSRunningApplication runningApplicationsWithBundleIdentifier:[self mainApplicationBundle].bundleIdentifier] objectAtIndex:0];
[app terminate];

Of course, I could add another observer in the main app, but I want to avoid that.

Got it, I had to add a temporary entitlement exception:

<key>com.apple.security.temporary-exception.apple-events</key>
<array>
    <string>mainAppBundleIdentifier</string>
</array>

If you place your apps in an Application Group you can send a signal to the main app to terminate itself.

The recommended way to IPC in 10.8 is using NSXPCConnection.

See the code at Sandboxing with NSXPCConnection
