How do you get the list of all supported document types in a Cocoa app, programatically?
I expected to find this in NSDocumentController but the closest thing appears to be documentClassNames, a list of NSDocument subclasses.

EDIT 1:
If you open Project.-Info.plist then there you can find Document types.
And this is written is a plist (key-value pairs) you can simply get those values.
NSDictionary *infoDict=[[NSBundle mainBundle] infoDictionary];
NSArray *extensions=[infoDict valueForKeyPath:@"CFBundleDocumentTypes.CFBundleTypeExtensions"];
NSLog(@"ext:%@",extensions);

Doesn't that assume that I know the types beforehand? – hpique Mar 12 '13 at 09:37

Its your application and you only set what files it is going to read, isn't it :) – Anoop Vaidya Mar 12 '13 at 09:40

No, it's not my application. I'm developing a framework that will be used by the application. – hpique Mar 12 '13 at 10:24

I don't know the application beforehand, Anoop. I don't have access to its plist. – hpique Mar 12 '13 at 10:55

There's an -infoDictionary call on NSBundle--that will give you the bundle's plist. Call it on the main bundle after your framework is loaded – nielsbot Mar 12 '13 at 11:01
