uicollectionview

问题 I basically want to copy Instagrams and Twitters profile pages. If I add a CollectionView to the bottom half, the CollectionView only scrolls on the bottom half of the page. The cells do not go all the way to the top and consume the profile statistics in the process. How can I make it so the profile statistics are consumed while scrolling, and the collection view takes up the whole screen? I can't seem to figure out how to make it so the cell only takes up the bottom half while the collection

问题 I am working on an app in which the user has access to different lists. I will show some pictures for a better understanding.

问题 So far, I made my collection views which scroll horizontally in either left or right.I added UICollectionViewCells into one UICollectionView. My problem that I'm having is trying to find the right settings to make the cards stack on top of the first card, as demonstrated in the photo below.

问题 My aim is to display a row of lazy loaded thumbnails (number not known) using a UICollectionView , the user can then scroll the thumbnails horizontally. I am using the code below to achieve close to what I am after but I am getting an error.

问题 I have a strange problem when tapping a single UICell in UICollectionView and then scrolling down or up in the UICollectionView I see that more one cell is selected. The other cells that are selected that were not tapped seem to be randomly selected throughout the UICollectionView layout. I have 3 columns of cells and many rows in the UICollectionView. In my code I have the following: - (void)collectionView:(UICollectionView *)myCV didSelectItemAtIndexPath:(NSIndexPath *)indexPath { LogInfo(@

问题 This is a follow-up from this question. Thanks so much to @rmaddy and @LeoDabus for your help thus far!
