Dashed line border around UIView

🎉📝 Welcome to my tech blog, where we break down complicated problems and make them easy to understand! Today, we're tackling the question: How can we add a dashed line border around a UIView? 🤔💭

So, you want to make your UIView stand out by giving it a cool dashed line border like the one in the provided image? 🤩🖌️ No worries! I've got you covered with some easy solutions.

Common Issues & A Specific Problem

The common issue we encounter when trying to add a dashed line border is that there is no direct property or method in the UIView class to achieve this effect. 😱🚫

However, we can solve this problem by utilizing the CALayer class, a powerful tool for manipulating the visual properties of our views.

Easy Solutions 💡

Solution 1: Creating a Dashed Line Border Using CAShapeLayer

One approach is to create a CAShapeLayer object and set its lineDashPattern property to specify the dashed pattern we desire. Let's dive into the code:

let dashedBorder = CAShapeLayer()
dashedBorder.strokeColor = UIColor.black.cgColor
dashedBorder.lineDashPattern = [4, 2] // Adjust the dash pattern to your liking
dashedBorder.frame = myView.bounds
dashedBorder.fillColor = nil
dashedBorder.path = UIBezierPath(rect: myView.bounds).cgPath
myView.layer.addSublayer(dashedBorder)

Explanations & Examples:

• We create a new CAShapeLayer object named dashedBorder. This layer will be responsible for creating our dashed line border.

• We set the strokeColor property to define the color of our dashed line. You can change it to any color you like! 🖌️🌈

• The lineDashPattern property allows us to define the pattern of the dashed line. In this case, we set it to [4, 2], which means the line should have a dash of length 4, followed by a gap of length 2. Feel free to adjust these values to match your desired style.

• Next, we set the frame property to match the bounds of our myView. This ensures that the dashed border is correctly positioned within the view.

• The fillColor property is set to nil to ensure that the dashed line is not filled with any color.

• Finally, we set the path property with a UIBezierPath object that represents the outer rectangular shape of myView. This defines the bounds within which our dashed line border will be drawn.

Solution 2: Using an Image with a Dashed Line Border

If you prefer a different approach, you can also use an image with a dashed line border and set it as the background of your UIView. Here's a code snippet to guide you:

let backgroundImage = UIImageView(frame: myView.bounds)
backgroundImage.image = UIImage(named: "dashedLineBorderImage")
myView.addSubview(backgroundImage)

In this solution, you'll need to create or find an image with the desired dashed line border. You can easily achieve this using graphic design tools like Photoshop or Sketch or by searching for pre-made images online. By setting this image as the background of your UIView, you'll achieve the desired effect!
