如何根据Swift 3中的“收藏夹视图内容高度"调整UIView高度? [英] How to adjust UIView height according to the Collection View Content Height in swift 3?

问题描述

我在调整项目中的UIView高度时遇到问题.我说明了这个项目.

I have a problem of adjusting the UIView height in my project. I illustrated the project.

让我解释一下我的项目图像.
每个Orange UIView的每个UIView都有跟踪，前导，顶部和底部约束和垂直间距.
但是，我将"Height"添加到每个UIView，因为如果不添加，它将给出错误并添加"Height"警告.
在UIView2中，我添加了3个容器视图.每个容器视图都有3个视图控制器. (数据1视图，数据2视图，数据3视图)
我在每个视图中都嵌入了集合视图.
问题在于，在数据3"视图中，有许多集合视图单元格数据.因此，应根据集合视图的内容增加Orange UIView的高度.
当前，如果用户单击数据3"分段控制按钮，则仅添加固定的高度常数(高度:800).
但是，我不想这样设置固定高度.
自上周以来，我一直在努力解决这个问题.直到现在我都无法解决.
有人可以帮我逐步解释吗?因为我不知道该怎么办.

Let me explain about my project image.
Each Orange UIView has trailing, leading , top and bottom constraints and vertical spacing to each UIView.
But, I add "Height" to each UIView because if I don't add, it gives error and add the "Height" warning.
In UIView2, I add 3 Container Views. Each Container Views has 3 View Controllers. (Data 1 View, Data 2 View, Data 3 View)
I embed Collection View inside in each views.
The problem is that in Data 3 View has many collection View cell data. So, the height of Orange UIView should be increase according to the collection view content.
Currently, I just add fixed height constant (height:800) if users click on the Data 3 segmented control button.
But, I don't want to set fixed height like this.
I've been trying to solve this problem since last week. I could not solve this till now.
Can anyone help me explain in step by step please? Because I have no idea of what should I do.

推荐答案

由于UITableView或UICollectionView从UIScrollView继承，因此它们基本上没有intrinsicContentSize.
有两种方法可以使高度与内容大小(可以滚动的空间)相同:

Since UITableView or UICollectionView inherit from UIScrollView they basically do not have an intrinsicContentSize.
You have two ways to make the same height as the content size (the space that you can scroll):

• 您可以对集合视图进行子类化，并覆盖intrinsicContentSize方法以返回contentSize和sizeThatFits:方法
• 在界面中创建一个高度限制并将其设置为等于集合视图的内容大小.

• You can subclass the collection view and override intrinsicContentSize method to return the contentSize and the sizeThatFits: method as well
• Create a height constraint in the interface and set it as equal to the content size of the collection view.
