Ios UICollectionView如何从解析查询

我有UICollectionView，我需要将图像下载到UIImage单元。我如何使用Parse来完成它？事实上，我需要类解析下载所有图像

这是我的源代码示例：

- (void)runQuery {
PFQuery *query = [PFQuery queryWithClassName:@"SwapPost"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    // You obviously need better error handling in here...
    self.myImage = objects;
    [self.myCollectionView reloadData];
}
 ];

}

已修复此代码的问题：

（NSInteger）集合视图中的节数：

(UICollectionView *)collectionView {
        // This is an assumption
        return [receivedObject count];
    }

(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
        self.imageCell.image = [NSArrayName objectAtIndex:indexPath.row];
    }

（NSInteger）收藏视图：

(UICollectionView *)collectionView {
        // This is an assumption
        return [receivedObject count];
    }

(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
        self.imageCell.image = [NSArrayName objectAtIndex:indexPath.row];
    }
