UICollectionView.reloadData或UICollectionView.deleteItemsAtIndexPaths使单元格隐藏但仍可单击

Question

I got a UICollectionView with several cells in it.

I deleted the first cell by clicking a button on it, it works good no matter I choose [UICollectionView reloadData] or [UICollectionView deleteItemsAtIndexPaths:] .

Now the following cells will move forward, so the first cell now would be the second one before the deletion, easy to understand, right?

Now comes the weird part:

1. I click on the first cell's delete button, it shows:

     <MyCell: 0x7fc5de566590; baseClass = UICollectionViewCell; frame = (220 20; 80 104); alpha = 0; hidden = YES; layer = <CALayer: 0x7fc5de566740>> 

2. I print the visible cells:

    < __NSArrayM 0x7fc5de655830>( < MyCell: 0x7fc5de55c060; baseClass = UICollectionViewCell; frame = (20 134; 80 104); layer = < CALayer: 0x7fc5de55c210>>, < MyCell: 0x7fc5de635290; baseClass = UICollectionViewCell; frame = (120 134; 80 104); layer = < CALayer: 0x7fc5de635440>> ) 

see? the cell I clicked on is actually that one been deleted, unless it's NOT! it has a flag hidden = YES , and it has a frame and superview also(yes the superview is the collection view).

Now that brings me problem because I meant to delete this guy MyCell: 0x7fc5de55c060.

So any clue on this? Thank you!

Answer 1

Problem solved. It's because I override hittest in MyCell. I didn't expect that deleted cells would still be subview of the collection view.
