有了Objective，我正在开发一款针对iOS 11的单视图应用程序，它有一个视图控制器/视图.基本上.在视图顶部的故事板上，我删除了一个WebKit视图(WKWebView).
我看到模拟器和运行iOS 11.0.1的iPhone6都崩溃了:
Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named WKWebView'个
我还需要什么其他东西才能让它工作吗？从故事板唤醒后，似乎无法实例化WKWebView.
其他详情:
- Xcode版本9.0 9A235
- 当我从故事板中删除WKWebView时，崩溃就消失了
- App Base SDK——最新的iOS(iOS 11)；部署目标11.0
- 使用WebView(已弃用)--UIWebView，它可以工作
- 我没有try 手动实例化它
