subclassing UICollectionViewFlowLayout

I am creating my own flowlayout but I am having problems getting the correct collectionViewContentSize, my data is an array of arrays, 5 arrays an each array have multiple items.

Is this correct numberOfItemsInSection:0 ? or do i need check all the arrays to find the array that have more items and then calculate xSize with the items on that section ? 

-(CGSize)collectionViewContentSize {

NSInteger xSize = [self.collectionView numberOfItemsInSection:0] * (itemWidth + space); // "space" is for spacing between cells.
NSInteger ySize = [self.collectionView numberOfSections] * (itemHeight + space);

NSLog(@"size %f, %f", xSize, ySize);
return CGSizeMake(xSize, ySize);

}

Thanks.

You have both axis being set. Typically, you only need to set one axis (the scrolling axis) because the screen edge (or the edge of your collectionView) in the non-scrolling direction will be set for you. OTher than that, yeah, you'll have to go through each array to get a total height.
