iOS: Multi-line UILabel in Auto Layout
📱 iOS: Multi-line UILabel in Auto Layout Solution Guide
Are you struggling with achieving the desired layout behavior for multi-line UILabel in Auto Layout on iOS? 😫 Don't worry, we've got you covered! In this guide, we'll address common issues and provide easy solutions to help you master this Auto Layout challenge. 💪
The scenario we'll be addressing is similar to the one described by a fellow developer who shared their layout in Interface Builder (IB). Let's dive in! 🏊♂️

Problem:
The top label, referred to as the title label, can have an unpredictable number of lines of text. The goal is to have the title label display all lines of text while maintaining proper layout of the other labels and the small image below it. We have set vertical spacing constraints between the labels and small image and also applied top and bottom spacing constraints.
Solution:
To achieve this desired layout behavior, follow these steps:
Adjust the number of lines on the title label: In Interface Builder, select the title label and set the number of lines property to 0. This allows the label to display an unlimited number of lines.
Set the Auto Layout constraints: Select the title label and apply a top spacing constraint from the label to its superview (possibly a container view). This ensures that the label is positioned at the top. Similarly, set the bottom spacing constraint between the small image and its superview to keep it at the bottom. Remember, the white UIView container should have no height constraint, allowing it to stretch vertically to accommodate its subviews.
Configure the vertical spacing constraints: Select the other two labels and the small image. Apply vertical spacing constraints between each of these elements and the title label. This ensures that they are positioned correctly below the title label, regardless of its size.
Auto Layout will handle the rest: With the appropriate constraints in place, Auto Layout will automatically adjust the height of the title label based on the amount of text content. The other labels and the small image will reposition themselves accordingly, maintaining the desired layout behavior.
And voila! 🎉 You have successfully achieved a multi-line UILabel within Auto Layout, accommodating various text sizes dynamically. No need to worry about setFrame methods or compromising on Auto Layout constraints.
Conclusion:
With these easy steps, you can have a dynamic multi-line UILabel in Auto Layout without breaking a sweat! 🙌 Feel free to explore further customization options and enhance your app's user interface.
