Objective-C: Get supported file extensions for a file type

I was wondering is there is a way of retrieving in Objective-C (MAC & IOS) all the supported extensions for a file type.

For example, I need to know all the file formats supported for graphics in IOS.

Thanks in advance.

Mikywan.

I have not used it myself but I think you can get what you are looking for from the Launch Services API
