high frequency (0.01 sec) realoadAt call for UICollectionview bumps cpu usage to 100%

Question

I am looking to call collectionView.reloadItems(at: [IndexPath(item: middle, section: 0)]) at frequency of 0.01 second to just update single cell, but it bumps cpu usage to 100%.

Any suggestion is welcome to bring it down.

Answer 1

You should not do that, just need to get the cell at indexPath you want:

if let cell = collectionView.cellForItem(at: IndexPath(item: 10, section: 0)) as? `YourCollectionViewCellClass` {
    //Update cell data here instead of reloading
}
