Color Tint UIButton Image

How to Change the Color of UIButton Image using Color Tint

📸 Have you ever wondered how to change the color of UIButton images without having to create separate PNG images for each button? Look no further! In this guide, we'll explore how you can utilize the color masking feature of UIImage to effortlessly change the color of your buttons using color tint.

Understanding the Issue

🔍 The issue at hand is that the UIImage automatically adjusts its color to match the tint of a specific control, like UISegmentedControl. The author of the question is curious to know if this feature can be applied to other UI elements, specifically UIButton.

💭 Let's say you have a set of buttons with a uniform shape but different colors. Instead of creating multiple PNG images, you want to use a single image and change its color dynamically based on the button's tint or background color. This would not only save you time but also make your code more maintainable.

Finding the Solution

🔧 Luckily, there's a simple solution to achieve the desired effect using color tint:

1. Start by creating a UIButton instance and setting its image using a UIImage object.

2. Set the button's tintColor property to the desired color that you want to apply to the image.

3. Voila! The color of the UIImage will automatically adjust to match the button's tint.

let button = UIButton()
let image = UIImage(named: "your_image_name")

button.setImage(image, for: .normal)
button.tintColor = UIColor.red // Replace with your desired color

🎉 That's it! You've successfully changed the color of the UIButton image without creating separate images for each button.

Going Beyond

🧩 While the above solution works perfectly for most use cases, there might be situations where you want more control over the color tint. For example, you may want the image to retain some of its original colors while applying the tint effect.

🌈 To achieve a more customized color tint, you can utilize image rendering mode and set imageRenderingMode property of UIImage to .alwaysTemplate.

let image = UIImage(named: "your_image_name")
let tintedImage = image?.withRenderingMode(.alwaysTemplate)
let button = UIButton()

button.setImage(tintedImage, for: .normal)
button.tintColor = UIColor.red // Replace with your desired color

🔍 By setting imageRenderingMode to .alwaysTemplate, the UIImage will be rendered as a template image, which allows for dynamic color adjustment.
