我正在使用 WKWebView，当我尝试使用 HardWare KeyBoard 应用程序在 WebPage 中插入任何值时崩溃。当我用我的 外部键盘 按下 Shift + Any Other Key 时，它总是崩溃。
注意：- 我已经用 webview.keyboardDisplayRequiresUserAction 和 true 尝试了 false
我已经尝试过以下解决方案，但对我不起作用
WKWebView crashes if user answers an incoming iMessage。
WKWebview with the new iOS13 modal crash when a file picker is invoked。
iOS11 WKWebview crash due to NSInvalidUnarchiveOperationException
