iOS UICollectionViewCell

Question

I am trying to make the spacing between my cells = 5

In the iPhone 4s the UICollectionViewCell becomes a square but I need rectangle.

I need iPhone4s iPhone5 iPhone6 iPhone 6Plus the cell, but the width and height of the cell is always wrong. I don't know how to do it automatically.

This is my code:

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    return CGSizeMake(([UIScreen mainScreen].bounds.size.width - 20) /2, ([UIScreen mainScreen].bounds.size.height) /3);
}

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
    return UIEdgeInsetsMake(5, 5, 5, 5);
}

What am I missing? Thanks in advance!

Answer 1

some change in your code will works fine

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
int itemWidth=([UIScreen mainScreen].bounds.size.width - 20)/2;
int intemHeight=itemWidth*2/3;
    return CGSizeMake(itemWidth, intemHeight);
}
