Creating a UIButton with Curved Edges and a Border in Swift

If you're working on an iOS application and want to give your buttons a more modern appearance, you might find yourself wondering how to create buttons that feature curved edges and borders. In this guide, we'll explore how to achieve this using Swift's powerful @ IBDesignable and @ IBInspectable properties.

Understanding the Problem

You might have encountered challenges in making a UIButton appear more visually appealing. Specifically, you want to add two main features:

Curved edges: Making the button's corners rounded.

Borders: Adding a distinct border to enhance the button's visibility and style.

Many developers struggle with this aspect of UI design, but fear not! We're here to guide you through the solution.

Solution Overview

To achieve a UIButton with both curved edges and a border, we can extend the UIButton class using a custom subclass. This subclass will allow us to utilize inspectable properties, making it easy to customize the button directly from the Interface Builder.

The Code

Here’s a simple implementation of a custom button class called MyButton:

Breakdown of the Code

1. @ IBDesignable and @ IBInspectable

@ IBDesignable: This allows your custom button to be rendered in Interface Builder, making it visually usable without writing code.

@ IBInspectable: This makes the properties customizable within the Interface Builder, allowing you to set the border color and width directly.

2. Properties Explained

borderColor: This property is used to specify the color of the button's border.

borderWidth: This property allows you to set the thickness of the button's border.

rounded: This property is a boolean that determines whether the button should have rounded edges.

3. Update Corner Radius

The updateCornerRadius function checks if the rounded property is true. If it is, it sets the button's corner radius to half its height, giving it a circular appearance. If false, it retains sharp corners.

Implementing the Button

Once you have your custom button, you can add it to your storyboard or programmatically create it. Don’t forget to set the borderColor, borderWidth, and rounded properties in the Interface Builder or programmatically in your view controller, depending on how you want to manage your button’s appearance.

Conclusion

Creating a UIButton with curved edges and a border not only enhances the design of your app but also improves user experience by making buttons more visually appealing. By implementing the MyButton class, you can easily customize your buttons right from the Interface Builder, streamlining your development process.

Feel free to experiment with different colors and widths to find the perfect design for your app’s theme. Happy coding!
