Placeholder in UITextView: How to Add a Placeholder to Your UITextView

📝 Hey techies! Are you struggling to add a placeholder to your UITextView? Just like the way you add a placeholder to a UITextField? Don't worry, I got your back! 😎 In this blog post, I'll show you some common issues that developers face when adding a placeholder to a UITextView, share easy solutions to those problems, and give you a compelling call-to-action to engage with us. So, let's dive in, shall we? 💪

Understanding the Problem: Adding a Placeholder to UITextView

The UITextView is a versatile component that allows users to enter large amounts of text. However, unlike the UITextField, the UITextView doesn't have a built-in property for a placeholder. 🤔

Common Issues Faced

1️⃣ Issue 1: No Placeholder Property

The first problem developers encounter is the absence of a placeholder property in UITextView. This can be frustrating, especially if you're familiar with using a placeholder in a UITextField. But fear not, my friend, for there are alternatives!

2️⃣ Issue 2: Placeholder Text Persisting After User Input

Another common issue is that the placeholder text remains visible even after the user starts typing. This can confuse users and make the UI look messy. But hey, with the right approach, we can tackle this problem head-on! 💪

Easy Solutions

Now, let's look at some easy solutions to these common issues. Implementing any of these should solve your problem.

1️⃣ Solution 1: Subclassing UITextView

One way to add a placeholder to your UITextView is by subclassing it and implementing custom logic. In your subclass, you can override the draw(_ rect: CGRect) method to draw the placeholder text when necessary. Additionally, you can use delegation or notifications to handle user input and hide the placeholder accordingly.

Here's an example of how you can subclass UITextView and add a placeholder:

class PlaceholderTextView: UITextView {
    var placeholder: String?

    override func draw(_ rect: CGRect) {
        super.draw(rect)
        if let placeholderText = placeholder, text.isEmpty {
            let placeholderAttributes: [NSAttributedString.Key: Any] = [
                .foregroundColor: UIColor.lightGray,
                .font: UIFont.systemFont(ofSize: 14)
            ]
            let placeholderRect = CGRect(x: 4, y: 8, width: rect.width, height: rect.height)
            placeholderText.draw(in: placeholderRect, withAttributes: placeholderAttributes)
        }
    }
}

2️⃣ Solution 2: Utilizing TextDidChange Notification

Another approach is to subscribe to the UITextViewTextDidChangeNotification and handle the placeholder logic within the notification observer. Whenever the text changes, you can check if the UITextView is empty and show or hide the placeholder accordingly.

// Add an observer for UITextViewTextDidChangeNotification
NotificationCenter.default.addObserver(self, selector: #selector(textDidChange(_:)), name: UITextView.textDidChangeNotification, object: nil)

// Handle the notification within the observer method
@objc func textDidChange(_ notification: Notification) {
    if textView.text.isEmpty {
        textView.addSubview(placeholderLabel)
    } else {
        placeholderLabel.removeFromSuperview()
    }
}
