How to Control Line Spacing in UILabel: Easy Steps for Perfectly Aligned Text

📢 Hey there tech enthusiasts! Are you struggling to control the line spacing in a UILabel? 😕 Don't worry, I've got your back! In this blog post, I'll walk you through the common issues faced and provide simple solutions to tame those unruly line breaks. Let's dive right in! 💪

The Dilemma:

So, you're working with a UILabel and you want to reduce the space between lines when your text wraps. You may have tried adjusting the frame size, font size, or even the number of lines, but the pesky gap remains. How can you achieve that perfectly aligned text with minimal spacing between lines? 🤔

The Solution:

Fear not, my friend! I'll provide you with two powerful techniques that will help you conquer this line spacing challenge effortlessly. 🎉

1. NSMutableParagraphStyle to the Rescue:

The first method involves utilizing the power of NSMutableParagraphStyle. 💪 Here's a snippet of code to help you get started:

let yourLabel = UILabel()

// Create an NSMutableParagraphStyle instance
let paragraphStyle = NSMutableParagraphStyle()

// Set the line spacing value to your desired spacing (in points)
paragraphStyle.lineSpacing = -4

// Apply the paragraph style to your label's attributed text
yourLabel.attributedText = NSAttributedString(string: "Your text goes here",
                                               attributes: [NSAttributedString.Key.paragraphStyle: paragraphStyle])

In the above example, we created an NSMutableParagraphStyle object and set the lineSpacing property to a value of -4 points. Adjust this value to achieve your desired line spacing. Simply assign this paragraph style to your UILabel's attributed text, and voila! You're done! 🎯

2. Custom Text Drawing with drawText(in rect: CGRect):

If the first method couldn't solve your problem, fret not! Here's another powerful technique that involves subclassing UILabel and customizing the text drawing process. Let's get coding:

class CustomLineSpacingLabel: UILabel {
  // Override drawText(in rect: CGRect) method
  override func drawText(in rect: CGRect) {
      let newRect = CGRect(x: rect.minX, y: rect.minY + yourDesiredSpacingValue,
                           width: rect.width, height: rect.height)
      super.drawText(in: newRect)
  }
}

In the code snippet above, we created a custom subclass of UILabel called CustomLineSpacingLabel. By overriding the drawText(in rect: CGRect) method, we have the freedom to adjust the rect parameter to modify the position of the drawn text. Simply change yourDesiredSpacingValue to your desired spacing in points, and you're good to go! 🚀
