WaterfallCollectionView

WaterfallCollectionView is custom layout for UICollectionView, based on Pinterest style. It supports (sticky or not) header supplementary view and decoration view.

...and now It's in development phase. :)

Sample usage

Setup FRGWaterfallCollectionViewLayout as UICollectionView layout in you view controller.

/*...*/
FRGWaterfallCollectionViewLayout *cvLayout = [[FRGWaterfallCollectionViewLayout alloc] init];
    cvLayout.delegate = self;
    
    cvLayout.itemWidth = 140.0f;
    cvLayout.topInset = 10.0f;
    cvLayout.bottomInset = 10.0f;
    cvLayout.stickyHeader = YES;
    
    [self.cv setCollectionViewLayout:cvLayout];		//cv is UICollectionView property
/*...*/

If you want to show section header you should implement delegate method

- (CGFloat) collectionView:(UICollectionView *)collectionView
                    layout:(FRGWaterfallCollectionViewLayout *)collectionViewLayout
heightForHeaderAtIndexPath:(NSIndexPath *)indexPath;
