🚫🔄 How to stop unwanted UIButton animation on title change?

Do you want to change the title of a UIButton without any unnecessary animations? Are you experiencing a frustrating delay or blink effect when updating the title? You're not alone! Many iOS developers have encountered this problem, especially when transitioning from iOS 6 to iOS 7 or newer versions. But fear not, we have some easy solutions that will put an end to these unwanted animations and make your UI transitions seamless. Let's dive in! 💪📱

The Problem Explained

In iOS 7 and onwards, UIButton titles are animated when changed using the setTitle(_:for:) method. However, sometimes these animations occur later than expected, resulting in an annoying blink or delay. This issue is not present in iOS 6, leaving developers scratching their heads.

Here's an example of the code causing the problem:

self.setTitle(text, for: .normal)

When this code is executed, the button's title will animate to the new value, but not always as smoothly as we would like. Let's explore a couple of solutions to combat this issue. 🤔🔍

Solution 1: Disable Animations

One way to stop the unwanted UIButton animation is to disable animations altogether. By temporarily changing the duration of the animation to zero, we can make the title change instant and seamless.

Here's how you can achieve this in Swift:

CATransaction.begin()
CATransaction.setAnimationDuration(0)
self.setTitle(text, for: .normal)
CATransaction.commit()

The CATransaction class allows us to group multiple layer-related operations into a single animated block. By setting the animation duration to zero within this block, we effectively disable the animation for the button's title change.

Solution 2: Use a Transition

Another approach to handle the unwanted animation is to use a transition between the original and new titles. This transition can be set to have no duration, resulting in an instant update.

Here's an example of how you can implement this solution:

UIView.performWithoutAnimation {
    self.setTitle(text, for: .normal)
    self.layoutIfNeeded()
}

By calling performWithoutAnimation on a UIView, we can make updates immediately without any animations taking place. Additionally, we need to call layoutIfNeeded to ensure the button's layout is refreshed correctly.

Take Action and Eliminate Unwanted Animations!

Now that you have easy solutions to stop undesirable UIButton animations on title changes, it's time to take action! Implement one of the provided solutions, or try both to see which one works best for your specific case.
