Determine if a path within an NSString is to a directory, or a file?

I have an NSString containing a path, but it could be either a file, or a directory.

Is there an equivalent to the Python os.path.isdir() and os.path.isfile() methods in Cocoa?

• See the NSFileManager Class Reference

  [[NSFileManager defaultManager] fileExistsAtPath:pathname 
                                  isDirectory:&directoryFlag];
  

  For example:

  NSString *file = @"/tmp/";
  BOOL isDir;
  if([[NSFileManager defaultManager]
       fileExistsAtPath:file isDirectory:&isDir] && isDir){
      NSLog(@"Is directory");
  }
