Playing with Collection Views is so much fun and challenging. One of the things I came across is using gradients with collection views.
Another challenge is, what if we need to add gradient to a
UICollectionViewCell on selection and remove it when the
UICollectionViewCell is de-selected.
So, do you find that challenging? Let’s see step-by-step how we can achieve that.
Before we start coding, let’s see what we already have 🧐 and how can we use that to solve our problem statement.
UICollectionViewCell’sproperties based on its selection state —Here we have already discussed how isSelected handles that.
Combining the above 2, now we’re left with “adding the gradient to cell when it is selected and removing it when it is de-selected”. We’re already halfway there, just need to put our knowledge in the right place. 🎯
Now that we know what actually needs to be done, let’s begin with some coding.
UICollectionViewCell, should implement 2 things,
That’s it. That’s the only code we require to get that working.
