【问题描述】：
我有 3 个视图：
-
UIImageView（空白，未设置图像） -
UITextViewisScrollEnabled设置为 false - 一个
UIView容器（灰色背景），其中包含UIImageView和UITextView
我正在尝试根据UITextView 的内容调整容器的大小。它工作得很好——但是一旦我设置了一个图像，容器似乎会根据UIImageView 调整大小。
我确实希望UIImageView 增长并填充容器视图的高度。我只是不希望它拉伸容器视图。这就是UITextView 的工作。这是我的约束的样子：
还有故事板代码：

And here's the image that I used。如何根据UITextView 而不是UIImageView 调整容器大小？
