How to hide/show UITextView in iOS Swift4

Question

textView.isHidden = true //false

I'm trying to hide/show UITextView by setting isHidden but it doesn't work properly. It does hide the UITextView but it still shows an area where the previous content was. See the image below. The right side is where I'm hiding, the view is hidden as we don't see pink view, but it looks like it still has content area in it. Any idea how to hide UITextView completely including it's content? I did search but couldn't find any solution.

Answer 1

将这些视图设置在单个堆栈中，因此如果您隐藏一个视图，它将自动将其容器与剩余元素一起排列。

Answer 2

你应该改变 textview 的高度
