Making an Element Not Affect Layout Elements in Swift (Akin to Absolute Positioning) (2024)

Abstract: In Swift UI development, we sometimes want to position an element without affecting the layout of other elements. In this article, we will explore how to achieve this using absolute positioning.

Introduction

Have you ever wanted to create an element that doesn't affect the layout of your Swift application, but still responds to user interactions? This article will explore how to create a clickable egg that doesn't affect the layout of other elements in your Swift application using akin absolute positioning.

Understanding akin Absolute Positioning

Akin absolute positioning is a technique that allows you to position an element relative to its nearest positioned ancestor, instead of relative to the normal document flow. This means that the element will not affect the layout of other elements in the document, and will remain in the same position regardless of the size or position of other elements.

How to Implement akin Absolute Positioning

To implement akin absolute positioning in Swift, you can use the following steps:

1. Create a new view and set its translatesAutoresizingMaskIntoConstraints property to false.
2. Set the view's frame property to the desired position and size.
3. Add the view to the desired superview.
4. Add constraints to the view to position it relative to its nearest positioned ancestor.

Creating a Clickable Egg

Now that you understand how to implement akin absolute positioning, let's explore how to create a clickable egg that doesn't affect the layout of other elements in your Swift application.

Step 1: Create the Egg Image

First, you'll need to create an egg image that you can use as the background for your clickable egg. You can create this image using any image editing software, or you can find a pre-made egg image online.

Step 2: Create the Clickable Egg View

Next, you'll need to create a new view that will serve as the clickable egg. Set the view's translatesAutoresizingMaskIntoConstraints property to false, and add the egg image as the view's background image.

let eggView = UIView()eggView.translatesAutoresizingMaskIntoConstraints = falseeggView.backgroundColor = .cleareggView.layer.cornerRadius = eggImage.size.width / 2eggView.layer.borderWidth = 2eggView.layer.borderColor = UIColor.white.cgColoreggView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(eggTapped)))eggView.layer.masksToBounds = trueeggView.backgroundColor = UIColor(patternImage: eggImage)

Step 3: Add the Clickable Egg to the View Hierarchy

Now that you have created the clickable egg view, you can add it to the view hierarchy using akin absolute positioning. First, create a new view that will serve as the container for the clickable egg. Set the container view's translatesAutoresizingMaskIntoConstraints property to false, and add it to the desired superview.

let containerView = UIView()containerView.translatesAutoresizingMaskIntoConstraints = falseself.view.addSubview(containerView)

Next, add constraints to position the container view relative to its nearest positioned ancestor. In this example, we will position the container view in the center of the superview.

NSLayoutConstraint.activate([containerView.centerXAnchor.constraint(equalTo: self.view.centerXAnchor),containerView.centerYAnchor.constraint(equalTo: self.view.centerYAnchor)])

Finally, add the clickable egg view to the container view, and add constraints to position it relative to the container view.

containerView.addSubview(eggView)NSLayoutConstraint.activate([eggView.widthAnchor.constraint(equalToConstant: eggImage.size.width),eggView.heightAnchor.constraint(equalToConstant: eggImage.size.height),eggView.centerXAnchor.constraint(equalTo: containerView.centerXAnchor),eggView.centerYAnchor.constraint(equalTo: containerView.centerYAnchor)])

In this article, you have learned how to create a clickable egg that doesn't affect the layout of other elements in your Swift application using akin absolute positioning. By following the steps outlined in this article, you can create custom user interactions that don't interfere with the layout of your application, providing a better user experience for your users.
