Unable to set width of UICollectionViewCell content with AutoLayout

Question

I'm creating a grid view using a collection view but some big iPhones have spacing on the right side.

I used the code below in collectionViewLayout method:

return CGSizeMake(cellSize / 4, cellSize /4)

Please see the image for more details.

Answer 1

The problem is solved after added below method:

- (void)viewDidLayoutSubviews {

    [super viewDidLayoutSubviews];
    //Invalidate collection view layout to make it recalculate
    [yourCollectionView.collectionViewLayout invalidateLayout];
}
