App Store, Sandbox and loadable code bundle

2014-06-23 Thread Trygve Inda
I have an app that normally exists as a System Preference Pane. To get it to
work in an app, and share the same code as the prefPane, I built a small
host app that simply loads the prefPane (a Mach-O bundle) with:

[self setPaneObject:[[[paneClass alloc] initWithBundle:paneBundle]
autorelease]];
if ([paneObject loadMainView])
{
[paneObject willSelect];

 // Add view to window and adjust size
 [window setContentSize:[[paneObject mainView] frame].size];
 [window setContentView:[paneObject mainView]];
 [window center];
 [window makeKeyAndOrderFront:self];

 [paneObject didSelect];
}


Both the app and the .bundle are codesigned. The .bundle resides within the
host app's package and the whole thing is sandboxed.

It works fine on my system, but is there any reason Apple will not approve
of this? The Mach-O code bundle gets loaded into the main app and becomes
part of it.

Has anyone submitted something to the App Store that works like this?

Thanks,

Trygve

I can't say definitively, but I think it's OK to load helper apps or other code 
into your own app from your own bundle as long as it's all signed. It's not 
really any different from loading a framework of your own and I've definitely 
had no problems doing that in an App Store app. The loaded code has the same 
restrictions as the host app, and can't touch anything outside the sandbox 
without the usual permissions.
