Creating folder in Documents with NSFileManager

Now we create folder  "PrivateDocuments" in "Documents" directory:

-(void) createFolder{

NSString *libraryDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

    NSString *privateDocs = [libraryDirectory stringByAppendingPathComponent:@"PrivateDocuments"];

    NSFileManager *fileMgr = [[NSFileManager alloc] init];

    if (![fileMgr fileExistsAtPath:privateDocs]) {

        NSLog(@"Does not exist");

        NSError *error = nil;

        [fileMgr createDirectoryAtPath:privateDocs withIntermediateDirectories:YES attributes:nil error:&error];

        NSLog(@"%@", [error description]);

    }

    [fileMgr release];

}
