Objective-C contentsOfDirectoryAtURL need filenames instead complete path

I´m using this piece of code to get the files contained in folder pathTo_Folder. What I get is something like this: "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Tech-2.jpg", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Tech-3.jpg", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Tech-4.jpg", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Terra-1.jpg", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Terra-2.jpg", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Terra-3.jpg", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Terra-4.png", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Terra-5.png", "file://localhost/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen/Terra-6.jpg"

I wonder if there is a way to get only the filename without the containing folder like "Tech-2.jpg"

NSString *pathTo_Folder = @"/Users/ronny/DEV/0200-ObjC4/ModernTimes/DrawingFun/linen";

NSFileManager *fileManager = [NSFileManager defaultManager];

NSArray *theFiles =  [fileManager contentsOfDirectoryAtURL:
                      [NSURL fileURLWithPath:pathTo_Folder]
                                includingPropertiesForKeys:[NSArray arrayWithObject:NSURLNameKey]
                                                   options:NSDirectoryEnumerationSkipsHiddenFiles
                                                     error:nil];

for( NSURL* fileURL in theFiles ) {
  NSString* filename = [fileURL lastPathComponent];
  // do things with the filename
}

As per the comments, if you just want the filenames:

// Note, this is not very efficient, and it's especially inefficient if
// you then go ahead and iterate the resultant array
NSArray* filenames = [theFiles valueForKeyPath:@"lastPathComponent"];

NSURL has a method lastPathComponent that does exactly what you need.
