具有动态高度多个UILabel的UIView

UIView with dynamic height multiple UILabel(具有动态高度多个UILabel的UIView)

问题描述

我正在制作一个包含 2 个 UILabel 的自定义 UIView，每个 UILabel 都具有动态高度.我无法为动态高度设置约束.(我是 Auto-Layout 和 iOS 方面的新手).

两个 UILabel 从 Top &底部，并与超级视图水平对齐.当我更改 UILabel 之一的内容时，UIView 和 UILabel 不会根据需要调整大小.

请提出建议.附上当前约束的屏幕截图.

我根据你的要求为你做了一个demo.从下面的链接下载它，<​​/p>

第 2 步:- 将约束设置为标签 1

1) 领先 2) 前 3) 尾随(来自它的超级视图)

第 3 步:- 将约束设置为标签 2

1) 领先 2) 前 3) 尾随(来自它的超级视图)

第 4 步:- 最棘手的从 UIView 给 UILabel 底部.

在 Xcode 10 及更高版本中 - 选择您的 UIView 和标签，然后从对齐约束部分选择底部边缘约束.

第 5 步:-(可选)将约束设置为 UIButton

1) 领先 2) 底部 3) 尾随 4) 固定高度(从主视图)

输出:-

注意:-请确保您已在 Label 属性中设置 Number of lines =0.

Edit1 :- 如果您想使用 BottomConstrain (>=) 增加尺寸，请查看下面的图片.

我希望这些信息足以理解 Autoresize UIView 根据 UILabel 的高度和 Autoresize UILabel 根据文本.

I'm making a custom UIView with 2 UILabel in it, with each UILabel having dynamic height. I'm unable to set constraints for dynamic height. (I'm new to Auto-Layout & iOS stuff).

Both UILabels are connected to each other from Top & Bottom, and are Horizontally aligned to superview. And when I change content of one of the UILabel, UIView and UILabel does not resize as required.

Please suggest. Attaching screenshots for current constraints.

I made a demo for you according to your requirement. Download it from below link,

Autoresize UIView and UILabel

Step by Step Guide :-

Step 1 :- Set constrain to UIView

1) Leading 2) Top 3) Trailing (From mainview)

Step 2 :- Set constrain to Label 1

1) Leading 2) Top 3) Trailing (From it's superview)

Step 3 :- Set constrain to Label 2

1) Leading 2) Top 3) Trailing (From it's superview)

Step 4 :- Most tricky give bottom to UILabel from UIView.

In Xcode 10 and above - Select your UIView and Label after that from the Align Constraint section select Bottom Edges constraint.

Step 5 :- (Optional) Set constrain to UIButton

1) Leading 2) Bottom 3) Trailing 4) Fixed Height (From mainview)

Output :-

Note :- Make sure you have set Number of lines =0 in Label property.

Edit1 :- If you want to increase size with BottomConstrain (>=) please check below Image.

I hope this info enough to understand Autoresize UIView according to UILabel's height and Autoresize UILabel According to text.
