How to return numberOfItemsInSection for two collectionView?

Question

My issues is that I am using the below code to return an images in collection view. ImageArray should return different number of images and claimImageArray should return different number of Images.But it does not work properly .Because it only display one image. Can anyone tell me what I did wrong in this ??

 - (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
    {
       if (collectionView==beforeParcelCollectionViews)
        {
             return [imageArray count];
        }
        if (collectionView ==  afterParcelCollectionView)
        {
            return [claimImagesArray count];
        }
           return 0;
    }

can you please provide the property declaration for beforeParcelCollectionViews and afterParcelCollectionView — Mayank Jain, Sep 18 '15 at 05:32
UICollectionView *beforeParcelCollectionViews; UICollectionView *afterParcelCollectionView; — Nisha Gupta, Sep 18 '15 at 05:35
I guess beforeParcelCollectionViews and afterParcelCollectionView both have a null value. Please put a breakpoint and check this. — Mayank Jain, Sep 18 '15 at 05:46
According to you beforeParcelCollectionViews and afterParcelCollectionView ... what does it contain so that it work properly ? — Nisha Gupta, Sep 18 '15 at 05:47
After adding breakpoint on beforeParcelCollectionViews and afterParcelCollectionView . i checked out that it contains UICollectionView. — Nisha Gupta, Sep 18 '15 at 05:52
There is nothing wrong with the code or the answer below. Your arrays must be having only 1 element each. — Nishant, Sep 18 '15 at 07:31
@Nishant I have checked my arrays count by NSLog.. They both have different images. But they return only one image. — Nisha Gupta, Sep 18 '15 at 07:42
@NishaGupta: Then the issue might be with the flow layout of the collection view which allows only 1 image. Not sure though due to lack to code. — Nishant, Sep 18 '15 at 07:44

I experienced the same problem. The following link solved my problem. I think you may set the same flow layout for both collectionView.
