How do I get a document UTI from a file path?

Question

I have a document path as an NSString. How do I get its UTI as an NSString? I currently use LSCopyItemAttribute but that requires an FSRef and all the functions for making an FSRef seems to be deprecated.

(Note: This is for Mac OS 10.8+.)

You will be able to get it using mobile core services framework. Refer the code below

NSString *path; // contains the file path

// Get the UTI from the file's extension:

CFStringRef pathExtension = (__bridge_retained CFStringRef)[path pathExtension];
CFStringRef type = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension, NULL);
CFRelease(pathExtension);

The code snippet is taken from here.
