Question

我使用以下代码将帖子上传到wordpress网站但有问题。

  TallyViewController *postVC = (TallyViewController *)[(UINavigationController *)[self presentingViewController] topViewController];
[postVC publishPostWithTitle:timeStampLabel.text content:descText.text image:self.image];
[self dismissViewControllerAnimated:YES completion:nil];

这是我收到的错误......
