Get the extension of a file contained in an NSString

Question

I have an NSMutable dictionary that contains file IDs and their filename+extension in the simple form of fileone.doc or filetwo.pdf. I need to determine what type of file it

Answer 1

//NSURL *url = [NSURL URLWithString: fileType];
NSLog(@"extension: %@", [fileType pathExtension]);

Edit you can use pathExtension on NSString
