【问题描述】：
我有一个位于标签栏内的表格视图。当我单击表格视图时，它会显示一个弹出视图控制器，如下所示：
但是，每当我导航到另一个标签栏时，弹出视图保持原样而不关闭它，当我回到上一个弹出视图时，它会显示一个深色背景，如下图所示：
我该如何解决这个问题？
*注意 = 我是 IOS 新手
添加子视图的代码：

【问题讨论】：
-
您的弹出窗口是常规 UIViewController 子类吗？
-
是的，它是@LGP。
-
你能分享一些代码吗？
-
@JenJose 我已经添加了我的代码，请您检查一下！
-
我有一个想法可以解决这个问题，但首先要说一下如何打开弹出窗口？ [1] UIView 或 [2] UIViewcontroller
