How to Enable Long-Press Text Selection in Your Ionic 4 App

Are you tired of struggling with text selection in your Ionic 4 application? If you're developing an app for iOS, you might have noticed that long-pressing on text doesn't always allow users to select, copy, or paste text as expected. This common issue can frustrate users and hinder the overall functionality of your app. In this guide, we'll walk you through a clear solution to enable long-press text selection in your Ionic 4 app.

Understanding User Selection in HTML/CSS

Before diving into the solution, it's important to understand how text selection works in the web landscape. In CSS, the user-select property is key for enabling or disabling text selection. However, getting it to work properly across various platforms, especially iOS, can be tricky.

Common Approaches That Don’t Work

As you may have discovered, there are several CSS snippets that developers often try to use, but they don’t always achieve the desired result. For example, the following snippets are frequently tested without success:

Another approach is creating a specific class for elements:

However, these may not work on all devices or under certain circumstances.

The Correct Solution

To enable text selection in your Ionic 4 app on iOS, make sure you follow these steps:

Step 1: Use the Correct CSS Rule

Instead of using text for the user-select property, try using auto. This often resolves the issue of long-press selection in your app.

Here’s the CSS rule to apply:

Step 2: Apply the CSS Class to Your Elements

Once you have defined the .text-select class, you need to apply it to the specific elements in your app that you want to make selectable. Here’s a sample usage:

This command makes it clear to the browser that the text should be selectable, allowing users to long-press, select, and copy text properly.

Conclusion

Enabling long-press text selection in your Ionic 4 app on iOS doesn’t have to be a headache! By adopting the .text-select class and using -webkit-user-select: auto;, you can enhance your user's experience significantly. Make sure to test on actual devices to verify that everything works as intended.
