2017 版 Laravel 系列入门教程（三）【最适合中国人的 Laravel 教程】

app/Http/Controllers/Admin/ArticleController.php index 方法不存在。让我们新增 index 方法： public function index() { return view('admin/article/index')->withArticles(Article::all()); } 这里的index方法是加在app/Http/Controllers/Admin/ArticleController.php 对吧？这里还是会报错，用的5.6. InvalidArgumentException View [admin.article.index] not found.

遇到个小问题，这2个报错怎么解决呢？

我分别修改为 let vc:UIViewController = self.viewControllers.last! let button:UIButton! = UIButton(type: UIButtonType.Custom) 也可以了
