Fixing Clickability Issues on UITableViewCell When Using Blinking Animation

When developing iOS applications, you might encounter a frustrating issue: your UITableViewCell starts blinking with a lovely animation, yet it becomes completely unresponsive to taps and swipe actions. This problem can be perplexing, especially when you are focused on creating a dynamic user experience. In this guide, we will discuss the root of this issue and provide you a detailed, step-by-step solution.

Understanding the Problem

In the provided code, the cell blinks when it is displayed on the screen. Here’s a snippet for your reference:

The blink() extension for views looks like this:

While this animation looks appealing, it inadvertently causes the cell to become not clickable. The default behavior in iOS is that user interactions are disabled during animations.

The Solution

The fix for this issue is straightforward. You can modify the options in your animation to allow user interactions. Specifically, you need to add the .allowUserInteraction option to your animation configuration.

Steps to Fix

Modify the Animation Options: Update your blink() function in the extension as follows:

Considerations

Animating Position Changes: If you plan to animate a view’s position (e.g., moving the cell across the screen), know that user interactions will still be tricky. Even with .allowUserInteraction, if the view is moving, it may not register taps correctly as it "jumps" to the destined position. Handling tapping on a moving view involves more complex logic.

Test Thoroughly: Always test your changes in a real device environment, as animations can behave differently in the simulator.

Conclusion

By simply adding the .allowUserInteraction option to your animation, you can resolve the clickability issue with your UITableViewCell while it performs the blinking animation. This simple adjustment will enhance the user experience of your application, making it both visually appealing and functional.

Now, you can create beautiful, responsive UITableViewCells that draw attention while remaining fully interactive. Happy coding!
