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 = NO; if([[NSFileManager defaultManager] fileExistsAtPath:file isDirectory:&isDir] && isDir){ NSLog(@"Is directory"); }

The important thing here is that the BOOL you pass into the isDirectory: portion of the method is the real BOOL to see if the file is a folder! The BOOL that is returned from the fileExistsAtPath:isDirectory: is just confirming if a file is a the path.
if the solution from htw doesn't work, try this:
NSString *file = @"/tmp/"; BOOL isDir NSDirectoryEnumerator *dirEnum = [[NSFileManager defaultManager] enumeratorAtPath:file]; while ((file = [dirEnum nextObject])) { [[NSFileManager defaultManager] fileExistsAtPath:file isDirectory:&isDir]; if(isDir){ NSLog(@"%@ is a directory", file); } }

Your solution is actually same as how's but I'm afraid it contains a bug - the 'file' you get is a RELATIVE PATH (relative to the "/tmp") and not an absolute path, hence using 'fileExistsAtPath:isDirectory' on it - may fail. this method works on absolute paths.
