Get UIScrollView to scroll to the top

📜 Scroll to the Top with UIScrollView: A Simple Guide

Have you ever found yourself deep down in a UIScrollView and in need of a fast-track ticket back to the top? Fear not, my tech-savvy friends! I've got you covered with a simple guide on how to achieve this magical scrolling feat. 🚀

🤔 The Common Dilemma: How to Scroll to the Top?

Let's set the scene. You have a long list of content in your UIScrollView, and your users are enthusiastically tapping and scrolling away. But wait! They suddenly realize they want to return to the top of the list in one swift motion. So, how can you make it happen? 🤷‍♂️

💡 The Solution: Code to the Rescue!

Luckily, there are several easy solutions to choose from, so you can tailor your approach to match your needs:

1. scrollToTop Property

The simplest way to enable scrolling to the top is by utilizing the scrollToTop property of UIScrollView. Just set it to true, and your UIScrollView will magically scroll to the top when users double-tap on the status bar. Voila! 🧙‍♀️

scrollView.scrollToTop = true

2. ScrollRectToVisible(_:animated:)

If you want more control over when and how the scroll happens, you can use the scrollRectToVisible(_:animated:) method. This method allows you to define a specific rect within your UIScrollView to scroll to. To scroll to the top, set the rect's origin to (0, 0) and the size to the frame size of your UIScrollView.

let topRect = CGRect(origin: .zero, size: scrollView.frame.size)
scrollView.scrollRectToVisible(topRect, animated: true)

3. setContentOffset(_:animated:)

For even finer-grained control, you can use the setContentOffset(_:animated:) method. This method allows you to set the content offset explicitly, scrolling your UIScrollView to the desired position.

scrollView.setContentOffset(.zero, animated: true)
