Objective-C: Extract filename from path string

Question

When I have NSString with '/Users/user/Projects/thefile.ext' I want to extract 'thefile' with Objective-C methods.

What is the easiest way to do that?

Thanks.

Answer 1

[[[string lastPathComponent] componentsSeparatedByString: @"."] objectAtIndex: 0];

Answer 2

From The NSString reference, you can use :

NSString* theFileName = [[string lastPathComponent] stringByDeletingPathExtension]

The lastPathComponent call will return "thefile.ext", and the stringByDeletingPathExtension will remove the .ext from the end.

Answer 3

If you're displaying a user-readable file name, you do not want to use lastPathComponent. Instead, pass the full path to NSFileManager's displayNameAtPath: method. This basically does does the same thing, only it correctly localizes the file name and removes the extension based on the user's preferences.
