Crash for recursive call on `setCollectionViewLayout(_:animated:)` about ibpcollectionviewcompositionallayout HOT 4 CLOSED

@ali0201
I tried to reset delegate for collectionView, it works! Thank you : )

    if #available(iOS 13.0, *) { } else {
      collectionView.delegate = nil
      if collectionView.delegate == nil {
        collectionView.delegate = self
      }
    }
    collectionView.setCollectionViewLayout(layout, animated: false)

from ibpcollectionviewcompositionallayout.

I found the solution.
You can try like this.

- (void)setViewModel:(GGViewModel *)viewModel {
    self.collectionView.dataSource = nil;
    self.collectionView.delegate = nil;

    if (!self.collectionView.dataSource) {
        self.collectionView.dataSource = self;
    }
    if (!self.collectionView.delegate) {
        self.collectionView.delegate = self;
    }
    [self.collectionView setCollectionViewLayout:layout animated:NO];
}

I have a feature to switch layout ( grid <-> list), so I call setCollectionViewLayout to switch.
But if I start from 'grid -> list -> grid', it will crash.
From the call stack, we can see two IBPUICollectionViewCompositionalLayout is called repeatedly.

p.s. in iOS version below iOS 13.

Example code as follow,

    switch layoutMode {
    case .grid:
      collectionView.setCollectionViewLayout(grid, animated: false)
    case .list:
      collectionView.setCollectionViewLayout(list, animated: false)
    }

call stack & error message as follow,

Hello, I also encountered this problem.
