swift中的WKwebview
我在xib中有一个viewController，我正在以编程方式添加web视图，我在视图中添加了背景色，并在xib中添加了ActivityIndicator，基本上，我想在web视图加载时显示此视图和activityIndicator，一旦web视图完成，我想隐藏视图并停止activityIndicator，当我在web视图中单击任何操作时，然后再次显示视图并启动activityLoader。我已将我的代码粘贴在任何建议下面，如果我有任何错误，请随时指导请允许我实现上述场景并帮助我 在web视图加载时，运行下面的代码是see dark view和NOActivityIndicator加载swift中的WKwebview,swift,Swift,我在xib中有一个viewController，我正在以编程方式添加web视图，我在视图中添加了背景色，并在xib中添加了ActivityIndicator，基本上，我想在web视图加载时显示此视图和activityIndicator，一旦web视图完成，我想隐藏视图并停止activityIndicator，当我在web视图中单击任何操作时，然后再次显示视图并启动activityLoader。我已将我的代码粘贴在任何建议下面，如果我有任何错误，请随时指导请允许我实现上述场景并帮助我 在web视图
