Programmatically open up Help Book.

Question

I want to trigger opening the help documentation of my macOS game.

In my info.plist I have:

Code Block         <key>CFBundleHelpBookFolder</key>
        <string>TrainHelp</string>
        <key>CFBundleHelpBookName</key>
        <string>Hexa Trains Help</string>

What code will kick off a (browser) window with the documentation?

I have included TrainHelp/ReadMe.html in my Resource bundle.

I ended up with this:

Code Block 	CFBundleRef mainBundle = CFBundleGetMainBundle();
	CFStringRef resourceName = (bridge CFStringRef)@"ReadMe";
	CFStringRef resourceType = (bridge CFStringRef)@"html";
	CFStringRef resourceDir  = (__bridge CFStringRef)@"TrainHelp";
	CFURLRef url = CFBundleCopyResourceURL( mainBundle, resourceName, resourceType, resourceDir );
	OSStatus s = LSOpenCFURLRef(url, 0);
	if (s) NSLog( @"Failed to open help documentation." );
	CFRelease( url );

Although it seems to me that this could have been done an easier way.
