Cell spacing in UICollectionView

How do i set cell spacing in a section of UICollectionView? I know there is a property "minimumInteritemSpacing" I have set it to 5.0 still the spacing is not appearing 5.0. I have implemented the flowout delegate method.

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section

return 5.0;

stil i am not getting the desired result. I think its the minimum spacing . Isnt there any way by which i can set the maximum spacing?

I know that the topic is old, but in case anyone still needs correct answer here what you need:

  1. Override standard flow layout.
  2. Add implementation like that:

    - (NSArray *) layoutAttributesForElementsInRect:(CGRect)rect {
        NSArray *answer = [super layoutAttributesForElementsInRect:rect];
        for(int i = 1; i < [answer count]; ++i) {
            UICollectionViewLayoutAttributes *currentLayoutAttributes = answer[i];
            UICollectionViewLayoutAttributes *prevLayoutAttributes = answer[i - 1];
            NSInteger maximumSpacing = 4;
            NSInteger origin = CGRectGetMaxX(prevLayoutAttributes.frame);
            if(origin + maximumSpacing + currentLayoutAttributes.frame.size.width < self.collectionViewContentSize.width) {
                CGRect frame = currentLayoutAttributes.frame;
                frame.origin.x = origin + maximumSpacing;
                currentLayoutAttributes.frame = frame;
        return answer;

where maximumSpacing could be set to any value you prefer. This trick guarantees that the space between cells would be EXACTLY equal to maximumSpacing!!
