How to Change the Color of Pagination Dots in UIPageControl 😎🔢

Are you stuck trying to customize the look of the pagination dots in your UIPageControl? Don't worry, we've got you covered! In this guide, we'll show you how to easily change the color or image of the pagination dots in UIPageControl, and we'll even provide some troubleshooting tips along the way. Let's dive in! 🏊‍♀️🔍

The Problem 🤔🔴

The standard UIPageControl in iOS has limited customization options, which can make it tricky to change the color or image of the pagination dots. This can be frustrating if you're trying to match the UI of your app or make it more visually appealing. Luckily, there are some workarounds to achieve the desired customization. Let's explore a few solutions! 💡🔧

Solution 1: Customizing the Current Page Indicator 🔮📎

By default, the current page indicator dot in UIPageControl is white, but we can override its appearance using the currentPageIndicatorTintColor property. Here's how:

pageControl.currentPageIndicatorTintColor = UIColor.red // Set your desired color here

You can replace UIColor.red with any other color of your choice. Feel free to play around and find the perfect color for your pagination dots! 🎨🌈

Solution 2: Customizing the Remaining Page Indicators 🌑📎

To change the color of the remaining page indicators (the dots representing pages that are not currently selected), we can use the pageIndicatorTintColor property. Here's how:

pageControl.pageIndicatorTintColor = UIColor.lightGray // Set your desired color here

Again, you can replace UIColor.lightGray with any other color that suits your app's design 🌟🎉

Solution 3: Using Custom Images 📸📎

If you want to go beyond simple color customization and use custom images for your pagination dots, you can do that too! UIPageControl allows us to set images for both the current and remaining page indicators. Here's how:

pageControl.currentPageIndicatorImage = UIImage(named: "custom-image-selected")
pageControl.pageIndicatorImage = UIImage(named: "custom-image-unselected")

Make sure to replace "custom-image-selected" and "custom-image-unselected" with the actual names of your custom images. 🖼️✔️

Troubleshooting Tips 🚧❌

If you're not seeing any changes in the pagination dot colors or images, make sure you're applying these customizations after setting the total number of pages in the UIPageControl. Additionally, check if the UIPageControl instance you're modifying is the one actually being displayed on the screen. It's easy to mistakenly create multiple instances!

Now that you've learned how to change the color or images of the pagination dots in UIPageControl, it's time to get creative and make your app's UI shine!
