Fixing Cursor Position Issues in UITextView for a Seamless User Experience

When developing apps for iOS, it's essential to ensure that user interactions are smooth and intuitive. A common problem faced by developers is a cursor position issue in UITextView. This occurs especially when users delete text or send messages, leading to an unexpected cursor position that can disrupt the user experience.

If you've found yourself frustrated with the cursor jumping unexpectedly in your UITextView, fear not! In this guide, we will explore a straightforward solution to keep the cursor at the starting position, regardless of the text length.

Understanding the Problem

Let's dive into the issue a bit deeper. When users interact with a UITextView:

After sending a message or deleting text, the cursor's position can change dramatically:

For a one-line message, it appears in the top left corner.

For longer messages, the cursor tends to settle in the bottom left corner.

This inconsistency can lead to confusion and hinder user experience. Even attempts to adjust cursor placement using methods like setMarkedText and automaticallyAdjustsScrollIndicatorInsets might not resolve the issue.

Proposed Solution

Implementing a Placeholder UILabel

One effective workaround involves using a UILabel as a placeholder on top of the UITextView. Here’s a breakdown of how you can implement this solution:

Step 1: Create a Placeholder UILabel

Add a UILabel on top of your UITextView. This label will act as a visual cue for users, indicating where to type.

Style the label appropriately (e.g., using a lighter color) so that it’s clear that it's a placeholder.

Step 2: Handle User Interaction

Enable First Responder Behavior: When the user taps on the placeholder UILabel, trigger the UITextView to become the first responder. This can be done with the following code snippet:

Step 3: Manage Visibility

Show or Hide the Placeholder: As users begin typing in the UITextView, make sure to hide the placeholder label. If the text view is empty and loses focus, you can show the placeholder again.

Benefits of This Approach

Enhanced User Experience: This method ensures that users always have visual guidance while typing, and the cursor placement remains predictable.

Simplicity: It's easy to implement and does not require complex adjustments to the text view's properties.

Customizable: You can style the label to match your app's aesthetic, enhancing your overall design.

Conclusion

In conclusion, cursor position issues in UITextView can be a frustrating experience, but by implementing a placeholder UILabel, you can create a smoother and more intuitive user experience. This solution helps maintain the cursor's position predictably while also providing visual cues for users as they interact with the text view.

Try this method in your next iOS project, and see the difference it makes!
