Changing the translatesAutoresizingMaskIntoConstraints property of a UICollectionReusableView that is managed by a UICollectionView is not supported, and will result in incorrect self-sizing. View:

collectionview在做insert的时候，有一定几率触发，出现过几次 ```swift collectionView.performBatchUpdates { collectionView.insertItems(at: idx) } completion: { _ in } ``` 参考1[https://stackoverflow.com/questions/30562493/no-uicollectionviewlayoutattributes-instance-for-layoutattributesforitematinde](url) 参考2[https://stackoverflow.com/questions/38005641/no-uicollectionviewlayoutattributes-instance-for-layoutattributesforsupplementa](url) 参考3[https://stackoverflow.com/questions/20436022/using-uicollectionview-performbatchupdates-with-a-uicollectionviewflowlayout](url)

控制台报以下错误，我搜了一下， 是设置translatesAutoresizingMaskIntoConstraints = false才会出现的。 Changing the translatesAutoresizingMaskIntoConstraints property of a UICollectionReusableView that is managed by a UICollectionView is not supported, and will result in incorrect self-sizing. View:
