Changing Placeholder Text Color with Swift

How to Change Placeholder Text Color with Swift

So, you have a beautiful design with a dark blue UITextField, but there's one problem - the placeholder text is barely visible due to its default dark grey color. 😓 Not to worry, we've got you covered! In this blog post, we'll walk you through step-by-step on how to change the placeholder text color using Swift.

The Problem

Before we dive into the solution, let's understand the problem first. When using Swift and not Objective-C, it can be a bit tricky to find the right solution to change the color of the placeholder text in a UITextField. But fear not, we'll show you how to do it effectively.

The Solution

To change the placeholder text color in a UITextField using Swift, follow these simple steps:

1. Create a subclass of UITextField and name it something like CustomTextField.

class CustomTextField: UITextField {

}

1. In the CustomTextField class, override the drawPlaceholder(in rect: CGRect) method to handle the drawing of the placeholder text.

class CustomTextField: UITextField {

    override func drawPlaceholder(in rect: CGRect) {
        // Set your desired placeholder text color here
        let placeholderColor = UIColor.red
        
        // Set the attributes for the placeholder text
        let attributes: [NSAttributedString.Key: Any] = [
            .foregroundColor: placeholderColor,
            .font: font as Any
        ]
        
        // Draw the placeholder text with the desired color and attributes
        if let placeholder = placeholder {
            let placeholderRect = rect.insetBy(dx: 0, dy: (rect.height - font!.pointSize) / 2)
            placeholder.draw(in: placeholderRect, withAttributes: attributes)
        }
    }
}

1. Now, you can use your CustomTextField class wherever you need to change the placeholder text color.

let textField = CustomTextField()
// Customize other properties of the text field as needed

Voila! 🎉 Your placeholder text color is now changed to your desired color.

Going Above and Beyond

Now that you know how to change the placeholder text color, why not take it a step further? Here are a few additional tips to enhance your UI:

• Consider using a dynamic placeholder text color that adapts based on the background color or theme.

• Experiment with different font styles and sizes for the placeholder text to make it stand out.

• Create a reusable extension for UITextField that allows you to easily change the placeholder text color without subclassing.
