UIStackView 中的多行标签

Multiline label in UIStackView(UIStackView 中的多行标签)

问题描述

当将多行标签(换行设置为自动换行)放入堆栈视图时，标签会立即失去换行并在一行中显示标签文本.

When putting multiline label (with linebreak set to Word Wrap) into a stack view, the label immediately loses the linebreak and displays the label text in one line instead.

为什么会发生这种情况?如何在堆栈视图中保留多行标签?

Why is this happening and how does one preserve multiline label within a stack view?

1. 在 UIView 中嵌入 UILabel(编辑器 -> 嵌入 -> 视图)
2. 使用约束使 UILabel 适合 UIView(例如，尾随空格、顶部空格和前导空格到超级视图约束)

1. Embed the UILabel inside a UIView (Editor -> Embed In -> View)
2. Use constraints to fit the UILabel to the UIView (for example, trailing space, top space, and leading space to superview constraints)

UIStackView 将拉伸 UIView 以使其适合，UIView 将限制 UILabel多行.

The UIStackView will stretch out the UIView to fit properly, and the UIView will constrain the UILabel to multiple lines.
