How to set UIButton title UILabel font size programmatically 🤔💻

Have you ever wondered how to programmatically set the font size of the title UILabel of a UIButton in your app? Look no further! In this blog post, we will dive into the common issues surrounding this problem and provide easy solutions to help you achieve the desired result. Let's get started! 🚀

The Issue at Hand 🤷‍♀️💭

Our anonymous friend had a specific problem: they needed to set the font size of the title UILabel of a UIButton programmatically. They were not sure how to go about it, and that's where we come in to save the day! 💪

Solution 1: Using UIButton.titleLabel.font Property 🖊📝

One way to set the font size of the UILabel for the button's title is by accessing the titleLabel property of the button and then setting the font property of the label. Here's a sample code snippet that demonstrates this approach:

let myButton = UIButton()

// Set the title text for the button
myButton.setTitle("Click Me!", for: .normal)

// Set the font size for the label
myButton.titleLabel?.font = UIFont.systemFont(ofSize: 18)

In the code above, we created a new button and set its title text using the setTitle(_:for:) method. Then, we accessed the titleLabel property of the button and set its font property to a system font with a size of 18 points.

Solution 2: Using UIFontMetrics for Dynamic Type Support 📏📐

If you want to support Dynamic Type, which allows users to customize the font size in their device settings, you can utilize the UIFontMetrics class. By using UIFontMetrics, the font size will automatically adjust based on the user's preferred font size. Here's an example of how to use UIFontMetrics to set the font size programmatically:

let myButton = UIButton()

// Set the title text for the button
myButton.setTitle("Click Me!", for: .normal)

// Set the font size for the label based on the user's preferred size
let metrics = UIFontMetrics(forTextStyle: .body)
myButton.titleLabel?.font = metrics.scaledFont(for: UIFont.systemFont(ofSize: 18))

In the code snippet above, we created a new button and set its title text using the setTitle(_:for:) method. We then created a UIFontMetrics instance for the body text style and used the scaledFont(for:) method to scale the system font with a size of 18 points based on the user's preferred font size.
